"I've come to talk over something with you, Heath," Hartley began, drawing a chair close to the table. "Can you remember anything at all of what you were doing on the evening of July the twenty-ninth?"

The Rev. Francis Heath dropped his paper, and stooped to pick it up; certainly he found the evening hot, for his face ran with trickles of perspiration.

"July the twenty-ninth?"

"Yes, that's the date. I am particularly anxious to know if you remember it."

Mr. Heath wiped his neck with his handkerchief.

"I held service as usual at five o'clock."

Hartley looked at him; there was something undeniably strained in the clergyman's eyes and voice.

"Ah, but what I am after took place later."

The Rev. Francis Heath moistened his lips and stood up.

"My memory is constantly at fault," he said, avoiding Hartley's eyes and looking at the ground. "I would not like to make any specific statement without—without—reference to my note-book."
