"Yes, sir," said Bob, nervously. "It's a sort of a long story. Shall I
tell it all?"

"Certainly. Come out here to the summer house."

They walked in silence to the little rustic house on the lawn and sat
down side by side on the rough wooden seat. Bob was excited, but still
determined that the best thing for him to do was to tell his father the
whole story. He knew his father would understand and see things from his
point of view; they were more like two brothers than a father and son.

"Hugh and I had the car out last night," said Bob, and then he began at
the beginning and related the entire story through to the end. He told of
their visit to the armory, their meeting with Harold on the bridge, the
narrow escape with the bomb, their decision to watch the Wernbergs'
house, their trip to the deserted house, the disappearance of the
automobile, and finally its strange return.

Mr. Cook listened intently throughout the whole narrative, one
exclamation as Bob told of the bomb episode being his sole interruption.

"That card must have been sent by the one that brought the car
back," said Bob.

"It would seem so," his father agreed, and fell silent, thinking.

"That was a close call you boys had with that bomb," he said finally.

"Yes, sir," said Bob.
