“Well, Herr Doctor,“ said Trezska. The impersonal term of address was employed knowingly, and Liebermann detected in its use a purposeful distancing. “Once again I am indebted. You know, I really think he was about to pull the trigger.”
Liebermann reached for von Bulow's hat and slipped it beneath his head. The insensible inspector's breathing was shallow, but not so shallow as to cause the young doctor alarm. Von Bulow would probably wake with blurred vision, dizziness, and nausea: nothing that twenty-four hours’ bed rest wouldn't put right.
“You're a spy-aren't you?” said Liebermann.
Trezska observed him without emotion. He grabbed the stair rail and pulled himself up.
“They call you… the Liderc?”
Trezska raised one of her eyebrows, indicating that she was impressed.
“And I presume,” Liebermann continued, “that this name was chosen because of your willingness to use your feminine charms in the service of your cause?”
“You have many flaws, Herr Doctor, but I had never, till this moment, counted prudery among them.”
Liebermann ignored her barbed riposte.
“Your mission,” he continued, “was to steal a document from General von Stoger-a top secret document called Studie U. The unwitting general was encouraged to expect your favors and invited you to his apartment. I wonder, did you always plan to kill him? Or did something go wrong that necessitated his murder?”
“I was supposed to keep the old man occupied, “ Trezska responded euphemistically, “while a comrade opened his safe. The fool made so much noise that von Stoger picked up a poker and went to see what was going on. My comrade panicked. It was most unfortunate.”
“And what about me?” said Liebermann. “Was I part of your mission too?”
“You flatter yourself, Herr Doctor. We met by chance.”
“In which case… you swiftly calculated that I might have some other use: the provision of an alibi, perhaps?”
“If this is to be a frank exchange of views,” said Trezska, “then I must admit, the idea did cross my mind; however, that was all. I sought your further acquaintance because I felt indebted to you. We Hungarians are nothing if not appreciative. Moreover, I found you very…” she paused before adding, “…desirable.”
A gust of wind lashed the side of Liebermann's face. A fresh cascade of water tumbled from the second story, contributing yet more volume to the existing downpour.
“I see from your expression,” said Trezska, “that you find my candid admission distasteful-unbecoming of a lady? Of course, if I were a man, you would think nothing of it. You are not nearly so enlightened as you suppose, Herr Doctor. Now, before I take my leave-which I really must-tell me, what are you doing here? I cannot recall issuing you with an invitation.”
“I came here to confront you.”
“Why? For what purpose?”
“To see if my deductions were correct.”
Trezska laughed. “Another of your flaws, Herr Doctor: intellectual vanity! Well, at the risk of aggravating your conceit, I must applaud you! Your deductions were indeed correct. Which brings me to my next question: How ever did you become so well informed? There are aides in the Hofburg who have never heard of Studie U. And as for my code name… If you hadn't rendered our poor friend here unconscious”-she gestured toward von Bulow-”I would be considering whether or not you had been recruited by the secret service.”
“And what if I was?” said Liebermann.
Before she could answer, a male voice resounded across the courtyard: “Don't move.”
Liebermann turned. Coming out of the arcade was a swarthy-looking young man. He was holding a gun and walking straight toward him.
