"Do as I say," he repeated curtly.
Frank, remembering, drew the yellow manila envelope from her bosom, and with out-stretched arm handed it to Pobloff.
The Russian took it in silence.

Then with a few quick strides he advanced to the alcohol lamp.

"A mere glance will be necessary, to make sure that we are not--mistaken!" He tore open the envelope with one long forefinger, and stooped to draw forth the contents.
It was then that Keenan sprang at him.

Frank at the moment, was marveling at the unbroken continuity of evidence linking her with her uncomprehending opponent.
The sudden leap and cry of Keenan sent a tingle of apprehension up and down her body.
