"Yes; it came to me in a flash when he first left me alone, only I was not certain in which parlor you would be waiting. I ran through the kitchen and down the back stairs; I helped the officers plan their decorations, and in that way learned of this private passage beneath the stairs. It was easy, but—oh, listen! they are in there now!"

We could hear voices through the intervening wall clearly enough to even distinguish words, as the speakers exercised little restraint. I felt the girl's slender figure press against me in the narrow space where we stood, and I clung to her hand, both remaining motionless and silent.

"The fellow has run, Grant," boomed some one hoarsely, "either afraid, or else what you say he is. See here, boy, did you see any one in here lately in scarlet jacket?"

"I don' just 'member, sah," answered a negro, hesitatingly. "I was busy over dar' cleanin' de side-boa'd."

"Well, he's not here now, that's certain," broke in Grant impatiently, "and we've been in all the parlors? What next, MacHugh?"

"Try to head him off before he can get out of the city, of course. That's his game, probably. Osborne, have Carter come here at once. Why didn't you nab the fellow upstairs, Captain? Fool play that, sending him down here."

"I didn't wish to create a row in the ball-room; he was with Claire Mortimer—"

"Oh, I see," laughing coarsely. "Something besides military duty involved, eh?"

"I'll trouble you to be a trifle more careful, MacHugh," Grant said stiffly. "The fellow did her a small service in the afternoon, and she couldn't refuse dancing with him, as he was in uniform, and apparently all right. I advise you to drop that part of the affair. Here's Carter now."

I could hear the click of the newcomer's spurs as he crossed the room. MacHugh chuckled.
