Jack, raised by his companion, got firm hold of the top of the wall, and by an effort clambered over.
"I'm over, all right," he said, in a low voice. "Get over yourself."
Marlowe looked cautiously up and down the street, till he was satisfied no policeman was in sight, then, making a leap, seized the wall, and, by the exercise of his strength, drew himself up, and then, of course, easily descended into the area.
"Here we are," said Jack, in a tone of satisfaction. "Now for work."
"The lights are all out," said Marlowe, softly. "I hope they are all asleep."
"It's likely they are."
"Did Julius say whether any of them slept in the basement?"
"He didn't find out."
"Well, we must risk it. We'll reconnoiter a little and see what's the best way to get in."
At length it was decided that a particular window afforded the easiest ingress. Of course it was fastened inside; but they were not novices, and this presented not the slightest difficulty to their practiced hands. With an instrument pointed with a diamond, they cut out the pane of glass just beneath, and, thrusting in a hand, Marlowe turned back the fastening. Then the window was softly raised, and both entered.
