“But I’m afraid boredom got the better of me, and I thought I’d see what else I could find out about Reles. Right away I discovered he was an American citizen and, on the face of it, an offense had been committed right there. As you probably know, only German-owned companies are allowed to tender for Olympic contracts, and, it transpired, Würzburg Jura Limestone had just outbid the local competition to supply stone for Berlin’s new stadium. I also found out that Reles seemed to have important connections here in Germany, so I resolved to see what was known about him in America. Which is why I contacted Liebermann von Sonnenberg.”

“What did the FBI tell you?”

“A lot more than I bargained for, to be honest. Enough to persuade me to check him out with the Vienna KRIPO. The picture I’ve built of Reles is based on two separate sets of information. And what I’ve managed to work out for myself.”

“You have been busy.”

“Max Reles is from Brownsville, New York, and he’s a Hungarian-German Jew. That would be bad enough, but there’s a lot more. His father, Theodor Reles, left Vienna for America at the turn of the century, most likely to escape a murder charge. He was strongly suspected by the Vienna KRIPO of murdering someone—perhaps several people—with an ice pick. It was apparently a secret technique taught to him by a Viennese Jewish doctor by the name of Arnstein. When Theodor settled in America, he married and had two sons: Max and his younger brother, Abraham.

“Now, Max has no convictions, although he was involved in the Prohibition rackets, as well as in loan-sharking and gambling. Since the end of Prohibition in March of last year, he’s built connections with the Chicago underworld. Little brother, Abraham, has a conviction for juvenile crime and is similarly involved in organized crime. He’s also believed to be one of the most cold-blooded killers in the Brooklyn mob and is reputed to use an ice pick for his murders, like his father. So skilled is he with this weapon that in some cases he leaves no trace.”

“How does that work?” I asked. “You stab a man with an ice pick, you figure it leaves more than just a bruise.”

Weinberger was grinning. “That’s what I thought. Anyway, there was nothing about this technique in the information I had from the FBI. But the Vienna KRIPO still have an old case file on Theodor Reles. You know, the father. Apparently what he used to do was ram the ice pick through the victim’s ear, right into his brain; and he was so good at it that many of his victims were thought to have died of a cerebral hemorrhage. Something natural, anyway.”

“Jesus,” I muttered. “That must be how Reles killed Rubusch.”

“What’s that?”
