"A professional job?" suggested Heath.
"Highly so," answered the Inspector, again blinking. "That is to say, the forcing of the lock was professional. And I would even go so far as to advance the opinion that the instrument used was one especially constructed for such illegal purposes."
"Could this have done the job?" Heath held out the poker.
The other looked at it closely, and turned it over several times.
"It might have been the instrument that bent the cover, but it was not the one used for prying open the lock. This poker is cast iron and would have snapped under any great pressure; whereas this box is of cold rolled eighteen-gauge steel plate, with an inset cylinder pin-tumbler lock taking a paracentric key. The leverage force necessary to distort the flange sufficiently to lift the lid could have been made only by a steel chisel."
