The Horse Feed Receipt on the Sealed Comparison Sheet

The horse feed receipt lay on top of the seal comparison sheet.

The red thread tied to the edge of the paper had three knots. The first knot meant the western ferry crossing, the second meant the purchase of horse feed, the third meant the village's consent. Without moving the receipt aside, Im Gwanpil looked at an angle at the pressed marks on the telegraph paper beneath it. The light coming through the window broke off at the rim of the seal impression. On one side the paper fibers had been pressed flat, deep enough to lie down, while on the other only ink had spread.

"Who brought this receipt?"

Jo Dokgu, standing at the door, did not unfold his arms.

"I'll talk if you put it in writing that the authorities won't seize and bind the man first."

O Chilbok and Bae Sangmun, junior operators at the telegraph bureau, drew their feet back every time they glanced at the door. There were no ropes. The herb storeroom behind the investigation office could be bolted from inside, and the location of their lodging was recorded only in the protection register. The moment the receipt was accepted, whoever submitted it could be dragged off along with them.

"I haven't written down a charge to arrest anyone on, so no one will be bound," Im Gwanpil said. "They'll be protected as witnesses."

"That paper turns into a charge the moment some higher up touches it with a brush."

"That's why I haven't kept only one original."

Im Gwanpil opened the protection register. He himself handled identity verification, while O Bokrye kept the lodging keys. He also recorded the daily wages lost during the protection period.

Jo Dokgu snorted.

"On paper, horses never tire and witnesses never go hungry."

"That's why I recorded the cost of the soup they ate today first."

Im Gwanpil reached a hand toward the receipt.

"Tell me the order of events."

Jo Dokgu finally came up to the table. He pressed his fingernail against each of the receipt's three knots, one by one.

"After the first cart crossed the ferry, feed was bought in the village. We got the blue thread back too, confirming that consent followed. But this isn't the receipt from that day. It's the price of feed the test cart bought the day before."

"Who said it was that day?"

"The shop's copyist. He copied the date from the departure schedule."

"What did you see yourself?"

"The wheel knows first. A paper can be fresh, but mud changes color once it dries. On the cart wheel this receipt was tied to, the mud from the North Gate the day before had dried and stuck fast. The mud from the western ferry is yellowish, mixed with sand."

"Is the dirt still there?"

"I scraped some off and kept it. But the dirt won't tell you which day it stuck."

Im Gwanpil did not record Jo Dokgu's words right away. He turned the receipt over and checked the stable owner's thumbprint and the feed storehouse ledger marks. The ledger noted only that one sack of horse barley had emptied that same evening.

"The receipt adds a purchase time, but it doesn't settle the cart's route."

"For an official, you're quick to admit what you don't know about the road."

"That's a separate matter."

Im Gwanpil set the receipt back down beside the seal comparison sheet. He needed to narrow down who could have passed through which room between the time the telegraph was stamped and the time the feed went out.

The right corner of the first telegraph paper had been scorched by lamp flame. The blackened edge had curled up about half a fingernail's width, and just inside it, the red seal ink lay broken off. Im Gwanpil laid a thin sheet of mulberry paper over it and rubbed it lightly with an ink stick. The outlines of three seals rose up, each in turn.

The first seal was deep, both the rim and the strokes of the characters. The second was pressed only at the bottom. The third was clear in shape but had left almost no mark reaching through the back of the paper. It was hard to believe all three had been stamped at the same table with the same force. That didn't mean all three were fake, either. The thickness of the ledger underneath, how dry the ink had been, and whose hand had pressed it could all change the depth.

Im Gwanpil asked O Chilbok.

"When did you first smell burning?"

"Before the first watch bell rang."

"When did you see the seal?"

"After that."

"Did you see who stamped it?"

O Chilbok opened his mouth, then closed it. When Bae Sangmun tried to rise in his place, Im Gwanpil raised a palm.

"Each of you speak only to what you saw. Don't fill in the other's blanks."

The silence stretched on. Outside, a soldier's scabbard knocked against the doorframe. O Chilbok's eyes moved toward the sound.

Im Gwanpil opened the door and sent the two soldiers back to the far end of the yard. In their place, he put O Bokrye in charge of the inner corridor. He had O Bokrye and the herb shop owner record entry and exit times together.

"I'll ask again. Did you see who stamped it?"

"I didn't see it," O Chilbok said. "It was already there by the time I brought back the second bundle of paper."

"Who handed it to you?"

"A relay runner with his face covered."

"Of his voice, hands, clothes, and identification tag, what did you make out?"

"There was ink on his right thumb. I didn't see a tag."

Ink on a thumb wasn't evidence enough to point to one person. Anyone at the telegraph bureau who handled paper could carry it. Im Gwanpil did not write down the name Yun Haejun. Instead he recorded the time and place of receipt, the color of the bundle's thread, and who had been in the room at that moment, each entered separately.

Bae Sangmun's account was different. He said he saw the bundle after the first watch bell, and by then the scorched corner had already crumbled, black powder falling to the floor.

"O Chilbok said it was before the bell."

"I heard the bell."

"From where?"

"From inside the battery room."

The battery room door was thick. On windy nights the North Gate bell was hard to hear. Im Gwanpil did not write this down as a lie, but made a note to verify the listening conditions. He would need to test again, at the same hour, in the same room, whether the bell could be heard.

If he sat the two of them face to face and pressed them, one would end up absorbing the other's memory. Such a statement would also be easy for someone above them to rewrite.

Im Gwanpil sent the two men to separate rooms. He kept their statements from being read by the other and gave them only the same list of questions. It would take until nightfall. Two more meals and O Bokrye's guard wages were added to the cost.

"Lock up even one of them and the higher ups would be pleased," Jo Dokgu said.

"I'll record the name of whoever is pleased, too."

"Then your own post will be the first to go."

"The loss of my post and the truth of the evidence are separate matters too."

Jo Dokgu did not laugh. From his robe he pulled out another folded sheet, the shop's own copy of the horse feed receipt. Beside the date was a short ink stroke that hadn't been on the one lying on the table.

"Why bring this out only now?"

"I meant to burn it if the authorities dragged off our driver just for having seen a relay runner."

"You mean you'd have destroyed evidence?"

"There's no reason to hand paper over to authorities who dispose of people first."

Jo Dokgu pulled a chair up and sat.

"But this time those two weren't put up as bait, so I'm handing over one sheet. It's not free, though. Put the name of whoever submitted the receipt into the protection register, and let the guild representative see the entry and exit records."

Im Gwanpil did not agree right away. If he showed the guild the entire protection register, the lodgings of other witnesses would be exposed too.

"I'll show only the entry and exit records of whoever submitted the receipt. Every other name will be covered."

"And if the authorities read under the covered ink later?"

"I'll make a redacted copy for viewing. The original will be sealed jointly by O Bokrye and the herb shop owner."

"Who pays for the trip?"

"If a day's work is lost because of the submission, it goes into the protection costs. The amount will be checked against the guild's ledger and the past freight rate sheet."

Jo Dokgu fingered the knot for a long while before writing his own name. The moment the brush tip left the paper, the receipt stopped being an object the inspector had seized and became evidence handed over under written terms.

The ink stroke on the shop's copy marked an evening settlement of credit. The stable owner said he only drew a line on items whose credit had been transferred into the ledger after sundown. The test cart had bought the feed before the first watch, and the settlement came after it. The receipt narrowed down only the purchase and settlement times, and nothing else.

Im Gwanpil compared the telegraph original against the stored rubbing once more. Under the first seal's scorched powder lay red ink. The second had pressed against the burnt edge, pushing the powder aside. The third seemed to have been pressed after a burnt fragment had already fallen away, but that could not be confirmed. Matched against the receipt's timing, one of the possible windows narrowed.

"So it's narrower than one watch period now?" Bae Sangmun asked.

"One possible window has narrowed. I still don't know who stamped it."

"Will you let us go back?"

"Not today."

Bae Sangmun's face hardened.

"Are you keeping us locked up under the name of protection?"

Im Gwanpil delayed his answer. Leaving the lodging carried a risk of being won over by someone else, but staying meant their daily wages stopped.

"The door can be bolted from inside, and you have the right to leave. But if you leave, you'll need to record your destination in the protection log so a guard can be assigned. If you refuse, I won't hold you by force. In that case I'll write down the reason protection was suspended along with the risk I couldn't prevent."

O Chilbok asked.

"Won't our names be put on the criminal register?"

"The witness register and the suspect ledger are kept separate. If anyone orders them merged, I'll keep that order too, word for word."

The two went back to talk it over. After a while, O Chilbok said he would stay in the herb storeroom, and Bae Sangmun said he would go out once to deliver medicine to his mother. Jo Dokgu assigned an old driver from the guild as his guide, not in place of an inspection soldier, but because someone was needed who knew the back alleys and the pharmacy's credit dealings that the inspectors did not. The round trip wage was recorded in the protection costs.

By sundown, the original with the burnt corner remained held between bamboo frames, and the blanks in the statements had not been filled in. There was no confession, no arrest. A demand notice from inspection headquarters circled the four characters for suspect secured in red.

Im Gwanpil wrote his answer beneath it.

Suspect unconfirmed. Physical evidence and witnesses kept separate. Any arrest order must be supplemented with the specific act and its grounds.

Jo Dokgu looked at the envelope and spoke.

"Those up top will think you came back with an empty cart."

"Not carrying a person doesn't make it an empty cart."

"That's a decent line, for an official."

Before he could step out the door, the sound of metal breaking came from the yard. The telegraph machine rang briefly, then went silent.

Baek Mujeong came in carrying a cracked battery plate in both hands. Black fluid dripped from his sleeve cuffs. One side of the plate had split lengthwise, and a thin scrap of zinc had been forced into the worn contact point.

"I've spliced the line back together with this. It won't hold long."

He emptied the remaining parts onto the table. Just two bent scraps of copper wire and three screws of the wrong size.

"The copper listed in the ledger isn't here, and there isn't a single matching battery plate."

The telegraph machine in the yard rang once more. The revived signal barely managed to print a single line before it died. Only the first character of Im Gwanpil's reply remained on the paper.
