"Very. Suppose you could get your father not to sleep here to-night for a change?"

"Wouldn't like to try. He fairly dotes on that comfortable soft bed. There's not another to compare with it in the house. I'm sure he wouldn't rest half so well on a harder one, and wouldn't give this one up unless he was compelled to do so by some unforeseen accident."

"Good," said Cleek. "Then there is going to be 'some unforeseen accident'—look!" With that he stripped down the counterpane, lifted the water-jug from the washstand and emptied its contents over the mattresses, and when the pool of water had been absorbed, replaced the covering and arranged the bed as before.

"Great Scot, man," began the lieutenant, amazed by this; but Cleek's hand closed sharply on his arm, and Cleek's whispered "Sh-h-h!" sounded close to his ear. "Keep your father up after everybody else has gone to bed, especially Aunt Ruth," he went on. "If she's not at hand, the damage can't be repaired for this night at least. Give him your room and you come in with me. Bridewell, I know the man; I know the means; and with God's help to-night I'll know the reason as well!"

Everything was carried out in accordance with Cleek's plan. The captain, trapped into talking by his son, sat up long after Miss Sutcliff and the one serving maid the house boasted had gone to bed, and when, in time, he, too, retired to his room, the soaked mattress did its work in the most effectual manner. Whimpering like a hurt child over the unexplained and apparently unexplainable accident, the old man suffered his son to lead him off to his own room; and there, unable to rest on the harder mattress, and suffering agonies of pain, he lay for a long time before the door swung open, the glimmer of a bedroom candle tempered the darkness to a sort of golden dusk, and the very double of Dr. Fordyce came softly into the room. It was Cleek, wrapped in a well-padded dressing-gown and carrying in addition to the candle a bottle of lotion and a fresh linen bandage.

"Why, doctor," began the old captain, half rising upon

the elbow of his uninjured arm. "Whatever in the world brings you here?"

"Study, my dear old friend, study," returned a voice so like to Dr. Fordyce's own that there was scarcely a shade of difference. "I have been sitting up for hours and hours thinking, reading, studying until now I am sure, very, very sure, Captain, that I have found a lotion that will ease the pain. For a moment after I let myself in by the partition door and found your room empty I didn't know where to turn; but fortunately your moans guided me in the right direction, and here I am. Now then, let us off with that other bandage and on with this new one, and I think we shall soon ease up that constant pain."
