Louis Tracy, The Message (Louis Tracy) — Chapter X. Hassan’s Tower… (1908)

To an active, barefooted Moor, with toes and fingers like the talons of a vulture, the climb would present no difficulty whatever. To a man whose nails were well kept, and whose toes would speedily be lacerated if not protected by boots, the scaling of the rough wall was no child’s play. But Warden began to crawl upwards without a moment’s hesitation. ”
