Gueguen leaned back and shoved out his jaw. “You’re pushing your luck, monsieur.”
Enzo delved into his shoulder bag, and brought out a green plastic Tupperware food box. He prised off the lid to reveal a dirty wine glass with polystyrene granules packed around it. “There are probably two or three sets of prints on this glass. I think one of them may belong to our murderer. I need you to pack it up securely and send it along with the shell casing to a colleague of mine in England. If there’s a match, then we’ve got our man.” He pushed a slip of paper with a name and address on it across the table. And then a sealed white envelope. “And put this in with it.”
Gueguen leaned forward and peered at the glass, then looked up at Enzo, eyes wide, intrigued. “Who do you suspect?”
“I don’t want to say anything until I am sure. I’d send it myself, but I don’t have time. I have to catch the train to Paris from Lorient in just under two hours. So I need to be on the next ferry.”
The gendarme frowned and shook his head again. “I still don’t understand. If there’s no fingerprint on the shell casing, how can it match with anything on the glass?”
“Because,” Enzo said, “there’s a chance that there is a fingerprint on the casing. Just not one that’s visible with conventional techniques. You see,…” he leaned forward, miming to illustrate his words as he spoke, “…the killer would have had to load the magazine with bullets, pushing each one in with his thumb against the pressure of the spring. And if he did that, then he will have left an invisible print.”
The skin around Gueguen’s eyes crinkled with consternation. “How?”
“Because the natural sweat present on the fingers reacts with the metal of the casing, in effect engraving the fingerprint invisibly into it. Sweat is a complex mix of water, inorganic salts like sodium chloride, and other oily compounds. These have a corrosive effect on the brass. And, in fact, while the heat generated by the process of firing the bullet will have obliterated any normal prints, it will actually have burned the sweat print more deeply into the metal. My colleague, Doctor Bond, has invented a technique for making those engraved prints visible.” Enzo smiled. “Deceptively simple, really. He applies a 2,500 volt electrostatic charge, then dusts the casing with a fine carbon powder which clings to the areas of metal corroded by the sweat. And, bingo! You have a fingerprint. Unfortunately the technique has not yet been granted a patent, so the only person in the world who can carry out this test is Doctor Bond himself. Which is why we have to send everything to him.”
The gendarme stared at him, almost open-mouthed. “That’s amazing, monsieur. The number of cold cases that could solve…”
Enzo nodded. “It’s a technique that can also be used for recovering fingerprints from exploded terrorist bombs. A conclusive way of catching the bomb makers. It’s going to revolutionise crime detection.” He stood up. “But for the moment, let’s just hope that it nets us Killian’s murderer.” He reached out a hand to shake Gueguen’s, then lifted his umbrella.
As he stepped from the boat to the pontoon he saw, through the mist of rain, the lights of the ferry approaching the harbour. The wind whipped at his umbrella, making it difficult to hold. He tipped it in the direction from which the wind blew, and teetered unsteady back toward the quayside. He was climbing the steps to the quay just as the ferry slipped through the narrow harbour entrance, a blast of its horn ringing around the little enclosed bay.
Fifteen minutes later, as he gazed from the rain-smeared window on the passenger deck, he saw Adjudant Gueguen emerging from La Boheme to make his way back to shore, Enzo’s Tupperware box tucked beneath his jacket.
It was, Enzo supposed, a long shot. The killer might have worn gloves when he loaded the gun. Or the magazine could have been preloaded. In either of those circumstances, any print recovered from the shell casing would not belong to the man who murdered Adam Killian.
He turned away from the window and found a seat, and when finally the boat had completed its turn in the relatively calm waters of the harbour and headed out again into the strait, he set his sights for the moment not on who murdered Killian, but why. The answer to that, he hoped, was waiting for him in Paris.
Part Four
Chapter Thirty-Two
Paris, France, November 2009
The Simon Wiesenthal Centre in the Rue Laugier was located in a four-story brick building opposite the narrow Rue Galvani. A stone-faced ground floor was accessed through an arched doorway. An equally stone-faced Gerard Cohen met Enzo in the entrance as arranged. He was a small man, clutching a large leather briefcase, and was completely bald. He had a lined, almost wizened face and small, black, suspicious eyes. He wore a dark blue suit that had seen better days. Enzo noticed how under the jacket the cuffs of his white shirt were frayed. His collar was crumpled, and his tie too tightly tied. He had a small, neatly trimmed silver moustache above too-full lips that were purple and shiny wet. Enzo thought that he must be at least seventy-five.
He shook Enzo’s hand with a firm but brief grip. Enzo reached for the door to hold it open for him. But he shook his head. “I no longer have an office here, monsieur.” He nodded along the street toward the Cafe Liberte on the far corner of the Rue Guillaume Tell. “But you can buy me a drink.”
He walked with quick, shuffling steps along the street, almost running, and Enzo had to work at keeping up with him. It was still dry in Paris, and mild. But a leaden sky presaged the coming rain that Enzo’s train had earlier outrun. They passed the Shri Ganesh Indian restaurant with its maroon canopies and crossed the street diagonally to the opposite corner, provoking a flurry of car horns.
Cohen took a seat by the window and Enzo slipped into a chair opposite. The cafe was also a tabac and sold lottery tickets, and so there was a constant stream of clients. It was noisy, customers barracking at the bar, the rumble of diesel engines out in the street, and the tinny, wasp-like buzz of motor-scooters whizzing past. Ideal for an exchange of confidential information. The place smelled of old alcohol and fried onions, but the smokers stood out on the sidewalks these days, so they were spared the fugg.
Enzo could see from the nicotine stains on his fingers that Cohen was also a smoker. He could smell the stale smoke that clung to his clothes but wasn’t certain if it was the enforced abstinence from cigarettes or some deeper insecurity that made him so nervous. The one-time Wiesenthal investigator kept glancing from the window toward the quincaillerie-droguerie opposite, as if there might be someone watching them from across the street. He constantly interlinked and unlinked his fingers on the table in front of him.
Enzo felt unsettled by his apparent edginess. “Is there any reason for us to be concerned about meeting like this?” he asked.
“Not that I know of, monsieur. But there are usually eyes on us.”
Enzo frowned. “Whose eyes?”
“The Nazis.” The word rolled off his tongue almost casually.
Enzo nearly laughed. “Surely those days are long gone? The people you went after following the war are dead or too old to be a threat.”
“Yes. But there is a new generation, monsieur. And they regard the people we hunted as heroes. And those who hunted them as vermin to be exterminated.”
The barman came to their table and they ordered beers.
Cohen fixed him with a penetrating stare. “So. How can I help you?”
“You know how you can help me. I want to know what you and Adam Killian wrote about in your exchange of letters. Why he came to see you.”
Cohen scratched his chin, and an alien-like tongue darted out to pass quickly over his already wet lips before withdrawing again behind yellowed teeth. He looked at Enzo pensively. “I checked you out, monsieur. You have quite a presence on the Net.”
“Yes,” Enzo agreed ruefully. “Unfortunately I do.”
“It’s where I live these days.”
Enzo frowned.
Cohen explained. “On the Internet. I spend most of my waking hours online. It’s incredible, you know, just
