"How do you know?"
"When I walked up the avenue I saw the clock on the church up by One Hundred and Fiftieth street. It was a quarter of eight."
"That fits the case exactly," Deever exclaimed. "It was a little after half-past seven when Burns saw Jarvis coming in from the garden."
"That is true."
"Will you arrest Jarvis now?"
"I will not," said Nick. "The evidence is not yet sufficient."
Deever made an impatient gesture.
"Remember," said Nick, "that an accusation of murder leaves an indelible stain. We cannot move too carefully."
"You will let him escape."
