The Winding Stair by A.E.W. Mason

"There's not the slightest reason for alarm," Gerard de Montignac declared testily in much the same tone which Colonel Vanderfelt was using to his wife nearly two thousand miles away. De Montignac was dining at the "popote" of his battalion in the permanent camp of Ain-Bourdja outside the walls of Casablanca, and more than once of late Ravenel's long absence had cropped up in the conversation with a good deal of shaking of heads. "Paul is a serious one," continued Gerard. "Too serious. That is his fault. He will not pack up and return until the last possible observation is taken, the last notes of value written down in his little book. But then he will. I am not afraid for him, no, not the least bit in the world. And who should be, I ask you, if I am not?"

He glanced round the mess but not one of his companions accepted his challenge. It was not, however, because they shared his confidence. Indeed every one was well aware that more than half of it was assumed. They respected a great friendship sealed nearly three years before on the bloody slopes of R'Fakha. De Montignac, with his squadron of Chasseurs, had ridden in that desperate charge by means of which alone the crest of the plateau had been held until the infantry arrived. The charge had been made down a hillside seamed with tiny gullies invisible until they gaped beneath the horses' feet; and the difficulties of the ground had so split the small force of cavalry that the attack became a series of scattered tourneys in which each overmatched trooper drove at a group of Moors armed with rifles and many of them mounted.
