Of course, by now I had realized the significance of the wig, and the tiara, and the Blue Grass perfume. I was reluctant to mention this to Dora, as I still hoped she might be persuaded to cooperate with me. But with each passing minute it was becoming clear that I had little choice now but to scare her into cooperation with what I now knew about her.

“Except that you’ve got no problem with being an accessory to murder, have you, Dora? Because you’ve already helped out with one murder, haven’t you? It was you that Heinrich Rubusch was with the night Max killed him with that ice pick. You were the blond in the tiara, weren’t you? Didn’t the guy mind when you showed him your mouse? That you weren’t a natural blond?”

“He was like any other Fritz when he sees a bit of mouse. All he cared about was that it squeaked when he stroked it.”

“Please tell me that Max didn’t kill him while you were doing it.”

“What’s it to you, anyway? He made no noise. There wasn’t even any blood. Well, maybe just a bit. Max blotted it up with the guy’s pajama jacket. But you couldn’t even see a mark. Incredible, really. And, believe me, he didn’t feel a thing. Couldn’t have. Which is more than I can say. Rubusch wanted a racehorse, not a girl. I had the marks of his hairbrush on my backside for days afterward. If you ask me, the fat pervert had it coming.”

“But the door was locked from the inside when we found him. The key was still in the door.”

“You opened it, didn’t you? I locked it the same way. Lots of hotel whores carry passkeys or key turners. Or know how to get hold of one. Sometimes a client pays you off without a tip. Sometimes they peel some leaves off a bush that’s too tempting to leave behind. So you wait outside for a while, and then go back in and help yourself to more money. Some hotel detective you are, Gunther. The other bull. What was his name? The drunk. Muller. He knew the score. It was him that sold me a key turner and a good passkey. And in return, well, you can imagine what he wanted. The first time, anyway. On the night Max killed Rubusch, I bumped into him, and was obliged to pin some notes on his coat.”

“Which were some of the same notes you’d been given by Rubusch.”

“Of course.”
