“On no grounds whatever. It’s just an idea I have, and may be all rubbish.”

Fuller nodded. “On the other hand it may be useful not to reject your idea, Dick. I shall watch and question Jotty if I get the chance.”

“Be careful, Alan. He is a sharp lad.”

“I’ll see that he does not get the better of me. Dick, isn’t it strange how suspicious one gets of everything when on a man-hunt?”

“Yes. But it’s natural enough. On a trail one always observes small signs to indicate the direction, and so everything around becomes of value in the way of evidence. However, you know what you have to do?”

“Yes. And you?”

“I shall keep in touch with Rotherhithe and Mother Slaig’s boarding-house and Moon. Whatever I learn you shall know. Good luck, Alan, to your hunting.”

“Ditto to yours, Dicky, and now clear out and let me get to work.”

Latimer tramped to the door and vanished with a friendly growl.
