"And we never even thanked you." The Mother-Superior turned to Saxham with outstretched hand and the smile that made her grave face beautiful. "What you must have thought!..."

"I looked for the person who had been so prompt, but you had vanished—where, nobody seemed to know," Lynette told him with her clear eyes on the stern, square face. "And then a man in the crowd called out, 'It's the Dop Doctor!' And I thought what an odd nickname!..." She broke off in dismay. Saxham had become livid. His grim jaws clamped themselves together, and the blue eyes grew hard as stone. One instant he stood immovable, the Waler's bridle on his left arm, his right hand clenched upon the old hunting-crop. Then he said very coldly and distinctly:

"As you observe, it is a queer nickname. But, at any rate, I had fairly earned——"

The bugle from the Staff headquarters sounded, drowning the rest of the sentence. The Catholic Church bell tolled. The other bells took up the warning, and the sentries called again from post to post:

"'Ware gun, Number Two! Southern Quarter, 'ware!"

The Krupp bellowed from the enemy's north position, and cleverly lobbed a seven-pound shell not far behind that rapidly-moving, distant pillar of dust, the nucleus of which was a little troop of cantering Irregulars, and not far in front of the lower, slower-moving cloud, the heart of which was a little knot of tramping Town Guardsmen. The shell burst with a splitting crack, earth and flying stones mingled with the deadly green flame and the poisonous chemical fumes of the lyddite. Figures scurried hither and thither in the smoke and smother; one lay prone upon the ground....

At the instant of the explosion Saxham had leaped forwards, setting his body and the horse's as a bulwark between Death and the two women. Now, though Lynette's rough straw hat had been whisked from her head by a force invisible, he saw her safe, caught in the Mother-Superior's embrace, sheltered by the tall, protecting figure as the sapling is sheltered by the pine.

"We are not hurt," the Mother protested, though her cheek had been cut by a flying flake of flint, and was bleeding. "But look ... over there!" She pointed over the veld to the prostrate brown figure, and a cry of alarm broke from Lynette.

"Oh, Mother, who ...?"

"It is a Town Guardsman," Saxham answered, his cold blue eyes meeting the wild frightened gaze of the pale girl. "Lord Beauvayse and the Irregulars got off scot-free. Reverend Mother, do not think of coming. Please go on to the Women's Laager. I will see to the wounded man, and follow by-and-by."
