Clinging to the wall with my feet and one hand, I unloosened one of the long leather straps of my trappings at the end of which dangled a great hook by which air sailors are hung to the sides and bottoms of their craft for various purposes of repair, and by means of which landing parties are lowered to the ground from the battleships.
I swung this hook cautiously to the roof several times before it finally found lodgment; gently I pulled on it to strengthen its hold, but whether it would bear the weight of my body I did not know. It might be barely caught upon the very outer verge of the roof, so that as my body swung out at the end of the strap it would slip off and launch me to the pavement a thousand feet below.
An instant I hesitated, and then, releasing my grasp upon the supporting ornament, I swung out into space at the end of the strap. Far below me lay the brilliantly lighted streets, the hard pavements, and death. There was a little jerk at the top of the supporting eaves, and a nasty slipping, grating sound which turned me cold with apprehension; then the hook caught and I was safe.
Clambering quickly aloft I grasped the edge of the eaves and drew myself to the surface of the roof above. As I gained my feet I was confronted by the sentry on duty, into the muzzle of whose revolver I found myself looking.
