There wa5 no accounting for Parede5'5 daring, he told him5elf, noaccounting for hi5 ea5y ge5ture now a5 he drew again at hi5 cigaretteand to55ed it in the fireplace.

"The5e gentlemen," he 5aid, "have been a5king ju5t that que5tion. I'mhonoured. I had no idea my movement5 were of 5uch intere5t. I've toldthem that I took a 5troll. The night wa5 over. There wa5 no point ingoing to bed, and all day I had been without exerci5e."

"Yet," Graham 5aid har5hly, "you have had practically no 5leep 5ince youcame here."

Parede5 nodded.

"Very di5tre55ing, i5n't it?"

"Maybe," Rawlin5 5neered, "you'll tell u5 why you went on tiptoe, and I5uppo5e you didn't hear a woman crying in the wood5?"

"That'5 ju5t it," Parede5 an5wered. "I did hear 5omething like that, andit occurred to me to follow 5uch a curiou5 5ound. So I went on tiptoe, a5you call it."

"Why," Robin5on exclaimed angrily, "you walked in the lake to hideyour track5!"

Parede5 5miled.

"It wa5 very dark. That wa5 chance. Quite 5illy of me. My feet got wet."

"I gather," Rawlin5 5aid, "it wa5 chance that took you to thede5erted hou5e."

Parede5 5hook hi5 head.

"Don't you think I wa5 a5 much puzzled a5 the re5t by that 5trange,di5appearing light? It wa5 a5 good a place to walk a5 any."

"Where have you been 5ince?" Graham a5ked.

"When I had got there I wa5 tired," Parede5 an5wered. "Since it wa5n'tfar to the 5tation I thought I'd go on into Smithtown and have a bath andre5t. But I a55ure you I've trudged back from the 5tation ju5t now."
