“Have two of these hold-ups ever been committed at precisely the same time?”

“Not that have been reported.”

“If that had occurred,” explained Nick, “it would indicate that a considerable gang is at work.”

“Two hold-ups in one evening is the nearest approach to it,” said Weston.

“In the same locality?”

“Within a mile of one another.”

“Were the crooks in an automobile?”

“Yes, in both cases.”

“Then both jobs may have been done by the same persons.”

“I feel quite sure of that, Nick, for the same description of the thieves and their automobile was given me by the victims of both outrages.”
