«Well, you have Freke's explanation.»
«Rot, Wimsey. You said yourself it wouldn't do.»
«Excellent. It won't do. Therefore Freke was lying. Why should he lie about it, unless he had some object in hiding the truth?»
«Well, but why mention it at all?»
«Because Levy, contrary to all expectation, had been seen at the corner of the road. That was a nasty accident for Freke. He thought it best to be beforehand with an explanation — of sorts. He reckoned, of course, on nobody's ever connecting Levy with Battersea Park.»
«Well, then, we come back to the first question: Why did Levy go there?»
«I don't know, but he was got there somehow. Why did Freke buy all those Peruvian Oil shares?»
«I don't know,» said Parker in his turn.
«Anyway,» went on Wimsey, «Freke expected him, and made arrangement to let him in himself, so that Cummings shouldn't see who the caller was.»
«But the caller left again at ten.»
