"Steve?" the Kite repeated. "I forgot him. Yeah—he keeps a little room up under the roof."

"Has he had it for as long as four years?" the young lady asked.

"Search me," the Kite shook his head.

But Louie the overalled, piloting us the first stage of our journey in a racketty old elevator that he seemed to pull up by a cable, so slow it was, grumbled an assent to the same question when it was put to him, and confirmed my belief that Skeels came into the hotel as soon as it was rebuilt, and had kept the same room ever since.

Miss Wallace seemed interested in this; but all the time we were making the last lap, by an iron stairway, to that roof-house we had seen from the top of the St. Dunstan; all the time Louie was unlocking the door there to let us out, instructing us to be sure to relock it and bring him the key, and to yell for him down the elevator shaft because the bell was busted, the quiet smile of Miss Barbara Wallace disturbed me. She followed where I led, but I had the irritating impression that she looked on at my movements, and Worth's as well, with the indulgent eye of a grown-up observing children at play.

On the roof of the Gold Nugget we picked up the possible trail easily; Clayte hadn't needed to go through the building, or have a confederate staked out in a room here, to make a downward getaway. For here the fire escape came all the way up, curving over the coping to anchor into the wall, and it was a good iron stairway, with landings at each floor, and a handrail the entire length, its lower end in the alley between Powell and Mason Streets. Looking at it I didn't doubt that it was used by the guests of the Gold Nugget at least half as much as the easier but more conspicuous front entrance. Therefore a man seen on it would be no more likely to attract attention than he would in the elevator. I explained this to the others, but Worth had attacked a rack of old truck piled in the corner of the roof-house, and paid little attention to me, while Miss Wallace nodded with her provoking smile and said,

"Once—yes; no doubt you are exactly right. I wasn't looking for a way that a man might take once, under pressure of great necessity."

"Why not?" I countered. "If Clayte got away by this means yesterday—that'll do me."

"It might," she nodded, "if you could see it as a fact, without seeing a lot more. Such a man as Clayte was—a really wonderful man, you know—" the dimples were deep in the pink of her cheeks as she flashed a laughing look at me with this clawful—"a really wonderful man like Clayte," she repeated, "wouldn't have trusted to a route he hadn't known and proved for a long time."

"That's theory," I smiled. "I take my hat off to you, Miss Wallace, when it comes to observing and deducing, but I'm afraid your theorizing is weak."
