“This is fantastic.” Willet said. “It’s unbelievable.”

“It’s unbelievable only because of the motive. Here we have two people, Mrs. Salzer and Sherrill, committing three murders between them, to say nothing of kidnapping Anona Freedlander and myself, to protect a girl from newspaper publicity. That’s what makes it unbelievable. I think there’s a lot more to this business than we know about. It seems to me these two are desperately trying to keep a very lively cat from hopping out of the bag, and I want to find out what kind of cat it is.”

“It’s not newspaper publicity they’re worrying about,” Willet said. “Look at the money that’s involved.”

“Yeah, but I still think there’s a strange cat we haven’t found yet. I’m going to hunt for it. Anyway, I’ll get on. I haven’t finished yet. The punch line comes last. Maureen told me when she came into her money, Sherrill reverted to type. He turned blackmailer. He said he would circulate the rumour that because she stole him from Janet, Janet shot her father and killed herself. But if Maureen bought the Dream Ship for him, he would keep quiet. She bought the Dream Ship: that’s why she converted the insurance money into bearer bonds. She gave the bonds to Sherrill. Imagine how the newspapers would scream if it got out that Maureen Crosby was the backer of a gambling-ship. Wouldn’t that drop the whole of the Crosby money into the Research Centre’s lap?”

Willet managed to look green without actually turning green.

“She bought the Dream Ship,” he said in a stifled voice.

“That’s what she tells me. She also said she was frightened of Sherrill, and at that dramatic moment Mr. Sherrill made a personal appearance. He announced he was going to put Maureen where no one would find her and dispose of me in the same way. I was beginning to argue with him when someone from behind bent a sap over my head, and I woke up in Salzer’s sanatorium. We won’t waste time going into what happened there. It’s enough that my assistant kidded Lessways he was a well-known writer and got himself invited to the monthly visit to the asylum with the City’s councilmen. He spotted me, and got out and we took Anona Freedlandcr with us. What we have to find out is whether Sherrill has carried out his threat to hide Maureen away. If she doesn’t show up tomorrow, my bet is she’s hidden away: probably on Sherrill’s ship. But if she does show up, then I’ll be inclined to think she’s in this business with the rest of them, and she took me to her house so Sherrill could get at me.”

Willet poured another drink with a hand that wasn’t too steady.

“I don’t believe that’s likely,” he said.

“We’ll see. If Sherrill is holding her, have you any power to stop her money?”
