Conceiving that robbery was contemplated, and knowing that promotion sprang not from prevention but cure, he was silent, and moved cautiously into the shade of a doorway to watch the proceedings above.
He had not, however, been long in this position when his serjeant approached.
"Hist!" said Ninety-nine, as the serjeant was passing.
"Who are you?"
"Ninety-nine."
"What are you up to?"
"Here!"
The serjeant joined him in the shade.
"Do you see that fellow there?" continued Ninety-nine.
"Good God!" exclaimed the serjeant. "Is it possible! Why, the slightest slip—a single moment's dizziness—would bring him to the ground, and dash his brains out."

"Here he comes," said the serjeant; "now watch him. He appears to have done his work. See how cool he is!—see how deliberately—how firmly he walks.—Now! He has stopped! Do you see him looking in at that window? It's opened for him. He enters. He's in. Now my boy, if plunder be your object, you're booked."
"That's safe to be his object," said Ninety-nine.
"I don't know," said the serjeant. "I think he's after one of the
