"We play the game by the rules the enemy himself laid down," Lanyard returned. "They would have sunk us without one qualm of pity—would, in all probability, have shelled our boats had any succeeded in getting off. They have done as much before, and will again. It is out of reason to insist that the captain risk his ship in the hope of picking up one or two drowning assassins."

"Risk his ship? How? They are helpless—"

"As a rule, U-boats hunt in pairs; always, when specially charged to sink one certain vessel. It was so with the Lusitania, with the Arabic as well; I don't doubt it was so in this instance—that we should have heard from a second submarine had not the destroyers opened fire when they did."

The woman stared. "You think that—?"

"That the Boche had specific instructions to waylay and sink the Assyrian? I begin to think that—yes."

This declaration affected the woman curiously; she shrank away a little, as from a blow, her eyes winced, her pale lips quivered. When she spoke, it was, strangely enough, in English so naturally enunciated that Lanyard could not doubt that this was her mother tongue.

"Then you think it is because…."

Of a sudden she wilted, clinging to the rail and trembling wildly.

Lanyard shot a glance aft. The disorder among the passengers was measurably less, though excitement still ran so high that he felt sure they were as yet unnoticed. On impulse he stepped nearer.

"Pardon, mademoiselle," he said quietly; "you are excusably unstrung. But all danger is past; and there is still time to regain your stateroom unobserved. If you will permit me to escort you…."
