Japp sighed. "Well, you've got a clear week to think in."
"And you will bring me any fresh developments that arise—the result of the labours of the hard-working and lynx-eyed Inspector Miller, for instance?"
"Certainly. That's in the bargain."
"Seems a shame, doesn't it?" said Japp to me as I accompanied him to the door. "Like robbing a child!"
I could not help agreeing with a smile. I was still smiling as I re-entered the room.
"Eh bien!" said Poirot immediately. "You make fun of Papa Poirot, is it not so?" He shook his finger at me. "You do not trust his grey cells? Ah, do not be confused! Let us discuss this little problem—incomplete as yet, I admit, but already showing one or two points of interest."
"The lake!" I said significantly.
"And even more than the lake, the boathouse!"
I looked sidewise at Poirot. He was smiling in his most inscrutable fashion. I felt that, for the moment, it would be quite useless to question him further.
