“How?” inquired Mr. Thompson.
“Through the roof scuttle. One of ’em—Blake I think it was—just discovered some finger marks in the dust around the scuttle, and it was found unhooked, so he’s pretty sure they came in from the roof.”
“How’d they get on the roof?” asked Jerry.
“That’s what they’ve got to find out,” went on the policeman.
“I wonder if I could take these friends of mine up and have a look?” ventured Mr. Thompson.
“Sure,” assented the other. “There’s not much to see though. I guess the best clews will be found down here.”
Bob wanted to take several snap shots of the wrecked safe, and Ned and Jerry waited for him. Meanwhile two or three detectives were observed poking about in the ruins, and the litter of paper for possible clews.
“Come on, Chunky, you’ve got pictures enough,” called Ned finally. “Let’s take a look at the roof, and you can make a snap shot there, and then we’ll get over to the store, buy the cylinder, and fix up our motorship.”
“All right,” assented the stout lad, closing his camera; and then Mr. Thompson led the boys up to the roof of the bank.
