“Bramson? A Bramson lived in Azarov’s apartment.”
“A coincidence, isn’t it?”
More than a coincidence, thought Korolev, given that Azarov had apparently denounced the former occupant in order to obtain the apartment. But Bramson and his wife had been arrested over a year before.
Ushakov picked up the firearm certificate from a small pile of papers and passed it to Korolev.
“A Derringer isn’t much good at a shooting range-its muzzle velocity is less than half of a Nagant’s, for example. Also these bullets most probably were manufactured before the Revolution-or maybe even before the German War. That’s why such a large-caliber bullet barely dented the table.”
“Yes, Chestnova said she was surprised by how little damage the bullet did. Inside his head, that is.”
“It will kill a man if it hits him in the right place from close up-which, of course, Professor Azarov is proof of.”
Korolev considered the evil-looking piece of lead, small enough to get lost in a man’s pocket, but not it seemed in his head.
“The low velocity-might it also explain the miss?”
“It might do. These guns aren’t completely inaccurate at short range-and the killer can’t have been more than a few feet away, given the size of the room; but, as I said, it’s not a precision weapon. Of course, I can’t be certain the weapon was Bramson’s Derringer, but it’s the only gun we know of connected to the building that takes bullets of this size.”
“I’m sure it’s the gun-it has to be. But Bramson was arrested by State Security-his wife as well. I’d have thought any weapon they’d owned would have been confiscated. If it wasn’t, however-perhaps it came into Azarov’s possession. Priudski’s fingerprints come with a confession, you see.” Korolev paused, collecting himself-remembering the script he had to keep to. “It indicates Shtange was the killer-perhaps he took the Derringer from Azarov and then used it on him.”
Ushakov gave him a quick glance and Korolev wondered, for the briefest of moments, whether the forensics man had spotted his skepticism about the Shtange story.
“I can’t tell you anything more without the gun itself, Korolev-that’s the fact of the matter. If you find it, I might be able to tell you something else-certainly I could tell you whether the bullet came from that gun. Might Shtange have hidden it somewhere?”
“Maybe,” Korolev said, while his mind focused, not for the first time that day, on whoever had been in the cramped ventilation space, one of the grilles to which had been at the precise angle that the bullet must have come from. That same grille, it had emerged when he’d examined it in Azarov’s apartment, had been unscrewed at some stage from the professor’s side, so that it could easily be opened from within the ventilation space. Korolev indicated the paper bag.
“What do you make of those?”
Ushakov opened the bag. “I make of it three former apples, mostly consumed. Should I make anything else of them?”
“I found them in a place the professor’s murderer may or may not have been hiding. Therefore I think these apples may or may not have been eaten by the killer.”
Ushakov picked up one of the apples by its stem.
“I can’t even tell you what size it was for certain, Korolev. Maybe if I knew exactly where it was found and could recreate the environment over a long enough period and had a sufficient number of different-sized apple cores, each eaten in exactly the same way, then I could tell. Maybe. If not, at least I’d have eaten a lot of apples.”
Korolev took the core from Ushakov and returned it to the bag, sighing. Then he tossed it into the nearby bin.
“I’m sorry, Korolev.”
“I thought it was a long shot.”
Ushakov pulled a glass box down from a shelf.
“I have something else however. Levschinsky spent a happy couple of hours putting this little work of art together for you.”
“What the hell is it?” Korolev asked, playing along-he had a good idea what it was.
“Your Dr. Shtange’s floor. This is the carpet, these the floor boards.” He indicated the layers of fabric and wood. “The blood goes through the gap between the boards, of course. Then there’s a layer of dust and rubble. Then the plaster ceiling. We cut that from the flat below so it’s probably accurate enough. Strangely the neighbor was quite keen to get rid of that part of his ceiling, and the building management committee was happy enough to arrange its replacement.”
The layers were balanced on a wooden frame that matched the distances between them. Much of the construction was caked with a dark-red, almost black crust.
“It’s not something he can be too precise on, but he reckons a minimum thirty minutes for the blood to go through. If anything, the summer heat would have made it take longer.”
Korolev leaned down to look more closely and, as he did so, caught a whiff of the caked blood that made him think better of the idea.
“That reduces the timings for us, thank you,” he managed to say, his stomach rolling as he straightened. Ushakov glanced up at him.
“Yes, it’s beginning to get a bit pungent, isn’t it?”
“A little.”
“Pig’s blood. Well, it’s going into the incinerator in about five minutes’ time, unless you want me to keep it.”
Korolev shook his head.
Ushakov smiled and returned the glass box to the shelf, then opened a small wooden box with brass corner fittings-inside was a rack of sample slides.
“As it happens, we came across something else interesting about the blood-not the stuff on the carpet, but where the murderer cleaned themselves-in the sink in the kitchen. We took some samples and not all the blood there was Shtange’s. Not, at least, unless he was a miracle of modern medicine and possessed two different blood groups.”
Korolev looked at the slide Ushakov was holding toward him. “I’ll take your word for it,” he said. “Tricky things, knives, particularly when you’re stabbing someone and there’s blood all over the handle. Easy to lose your grip and cut yourself.”
“Indeed. Find me the knife, of course…”
“And you could tell me more?”
“Yes, and if you have a suspect-I might be able to tell you something more again.”
Ushakov’s demeanor had been becoming increasingly serious as the conversation had progressed, and now it was close to funereal. He opened a drawer in his desk to remove from it a thick brown envelope. He put it on the tabletop and tapped it, as though considering something.
“You said you thought Dr. Shtange may have had something to do with the professor’s murder?”
“It seems that way.”
“But you’re not sure?”
“There are some inconsistencies.” Korolev chose his words carefully. “But it seems the story isn’t impossible. The doorman, Priudski, let Shtange into the apartment, it seems.”
“That’s interesting-because we’ve got one of Priudski’s fingerprints in Azarov’s study. On the door handle.”
Korolev shook his head sadly. “There’s an explanation, I’m afraid-he was in the apartment when the Militia arrived. The maid called him up.”
“We didn’t think to check if Priudski had been in Shtange’s apartment, of course.”
“Why would you?”
Ushakov tapped the envelope once again and Korolev wondered what the hell was in it.
“I can tell you half of Moscow had trundled in and out of that place by the time we got there. I’m presuming the blood in the sink belongs to the murderer, but who knows what our colleagues got up to in there over two whole days.”
“Nothing untoward, I’m sure,” Korolev said when the momentary pause lengthened.
“Of course not,” Ushakov said quickly.
“And the maid mentioned the blood in the sink,” Korolev said. “I’m sure it’s as you say.”
Ushakov finally picked up the envelope again, and sighed.
