Winds of the World by Talbot Mundy

The colonel of Outram's Own dropped into a club where he was only one, and not the greatest, of many men entitled to respect. There were three men talking by a window, their voices drowned by the din of rain on the veranda roof, each of whom nodded to him. He chose, however, a solitary chair, for, though subalterns do not believe it, a colonel has exactly that diffidence about approaching senior civilians which a subaltern ought to feel.

In a moment all that was visible of him from the door was a pair of brown riding-boots, very much fore-shortened, resting on the long arm of a cane chair, and two sets of wonderfully modeled fingers that held up a newspaper. From the window where the three men talked he could be seen in profile.
