“I say, Tony, do you really mean it?”

“Mean what?”

“About Cayley.”

“I mean what I said, Bill. No more.”

“Well, what does it amount to?”

“Simply that Robert Ablett died in the office this afternoon, and that Cayley knows exactly how he died. That’s all. It doesn’t follow that Cayley killed him.”

“No. No, of course it doesn’t.” Bill gave a sigh of relief. “He’s just shielding Mark, what?”

“I wonder.”

“Well, isn’t that the simplest explanation?”

“It’s the simplest if you’re a friend of Cayley and want to let him down lightly. But then I’m not, you see.”
