A Certain Dr Thorndyke by R. Austin Freeman

As the prisoner was withdrawn by his guard into the dark opening of the thicket, Osmond halted for a moment to look back across the river. Not a sign of the enemy was to be seen excepting the pall of smoke that hung over the wooded shore. But the reports of unseen muskets and rifles and the hum of slugs and bullets warned him of the danger of exposing himself -- though he, too, was probably hidden from the enemy by the dense smoke of the black powder. Accordingly he turned quickly and, plunging into the dark tunnel-like passage, groped his way forward, unable, at first, to distinguish anything in the all-pervading gloom. Presently he perceived a little distance ahead a cluster of the great bamboo stalks faintly lighted as if by a hidden fire or torch, and a moment later, a turn of the passage brought him in view of the light itself, which seemed to be a rough shea-butter candle or lamp, set on the ground and lighting up dimly the forlorn little band whose retreat he had covered.

This much he took in at the first glance. But suddenly he became aware of a new presence at the sight of which he stopped short with a smothered exclamation. Stockbridge, sitting beside his dead comrade, had uncovered his wounded leg; and kneeling by him as she applied a dressing to the wound was a woman. He could not see her face, which was partly turned away from him and concealed by a wide pith helmet; but the figure was -- to him -- unmistakable, as were the little, dainty, capable hands on which the flickering light shone. He approached slowly, and as Stockbridge greeted him with a wry grin, she turned her head quickly and looked up at him. "Good evening, Mr. Cook," she said, quietly. "What a fortunate chance it is that you should be here."
