Barbara went with me out into the flare of carnival illumination that paled the afterglow of a gorgeous sunset. No cars allowed on these down-town streets; even walking, we found it best to take the long way round. To our left the town roared and racketed as though it was afire.

Nothing said between us till I grumbled out,

"I wish I knew where c.u.mmings was keeping Eddie Hughes."

Barbara's voice beside me answered unexpectedly,

"Here. In Santa Ysobel. Eddie was at Capehart's fifteen minutes before you got there; he came for Bill. A gasoline engine at the city hall had broken down."

I pulled up short for a moment, and looked back at the town.

"Where'd he go?"

"With Bill, to the city hall. Eddie's one of the queen's guards. They're all to be at the country club at ten o'clock to review the grand march that opens the ball."

I mustn't let her dwell on that. I hurried on once more, and neither of us spoke again till I unlocked the study door, snapped on the lights, brought out and put on the table the 1920 diary and the little blue blotter--the last bits of evidence that I felt hadn't been thoroughly a.n.a.lysed. Barbara just dropped into a chair and looked from them to me helplessly.

"You've read this all--carefully?" she sighed.

It shook me. To have Barbara, the girl I'd seen get meanings and facts from a written page with a mere flirt of a glance, ask me that. What I really wanted from her was an inspection of the book and blotter, and a deduction from it. As though she guessed, she answered with a sort of wail,

"I can't, I can't even remember what I did see when I looked at these before. I--can't--remember!"

I went and knelt on the hearth with a pretext of laying a fire there, since the shut-up room was chill. And when I glanced stealthily over my shoulder, she had gone to work; not as I had ever seen her before, but fumbling at the leaves, hesitating, turning to finger the blotter; setting her lips desperately, like an over-driven school-child, but keeping right on. I spun out my fire building to leave her to herself.

Little noises of her moving there at the table; rustle and flutter of the leaves; now and again, a long, sobbing breath. At last something like a groan caused me to turn my head and see her, with face pale as death, eyes staring across into mine.

"It was Clayte--Edward Clayte--who killed Mr. Gilbert here--in this room."

The hair on the back of my neck stirred; I thought the girl had gone mad. As I ran over to the table and looked at what was under her hand, it came again.

"He did. He did. It was Clayte--the wonder man!"

"Do--do you deduce that, Barbara?"

"Did I?" she raised to mine the face of a sick child. "I must have.

See--it's here on the blotter: 'y-t-e,' that's Clayte. Double l-e-r; that's 'teller,' 'Avenue' is part of 'Van Ness Avenue Bank.' Oh, yes; I deduced it, I suppose. Both crimes end in a locked room and a perfect alibi. But--but--don't you see, if it is true--and it is--it is--we're worse off than we were before. We've the wonder man against us."

"Barbara," I cried. "Barbara, come out of it!"

"See? You don't believe in me any more," and her head went down on the table.

I let her cry, while I sat and thought. The broken sentences she'd sobbed out to me began to fit up like a puzzle-game. By all theories of good detective work, I should have seen from the first the similarity of these crimes. But Clayte, slipping in here to do this murder--and why?

What mixed him up with affairs here? And then the icy pang--d.y.k.eman had seen a connection--c.u.mmings had found one. With them, it was Clayte and his gang--and his gang was Worth Gilbert. I went and touched Barbara on the shoulder.

"I'm going to take you home now."

"Yes," tears running down her face as she stumbled to her feet. "I'm a failure. I can't do anything for Worth."

I wiped her cheeks with my own handkerchief and led her out. As I turned from locking the door, it seemed to me I saw something move in the shrubbery. I asked Barbara Wallace about it. She hadn't noticed anything. Barbara Wallace hadn't noticed anything!

I began to be scared for her. Solemn in the sky above boomed out the town clock--two strokes. Half past nine. I must get this poor child home. We were getting in toward the noise and the light when I felt her shiver, and stopped to say,

"Did I forget your coat? Why, where's your hat?"

"The hat's back there. I had no coat. It doesn't make any difference.

Come on. I can't--can't--I must get home."

I looked at her, saw she was about at the end of her strength, and decided quickly,

"We'll go straight through the Square. Save time and steps."

She offered no objection, and we started in where the bands played for the street dances, amid the raucous tooting of a thousand fish-horns, the clangor of cow-bells, and the occasional snap of the forbidden fire-cracker. As we turned from Broad Street into Main, I found that the congestion was greater even than I had supposed. Here, several blocks away from the city hall, progress was so difficult that I took Barbara back a block to get the street that paralleled Main. This we could navigate slowly. Here, also, everybody was masked. Confetti flew, serpentines unreeled themselves out through the air, dusters spluttered in faces, and among the Pierrettes, Pierrots, Columbines, sombrero-ed cowboys, bandana-ed cow-girls, Indians, Sambos, Topsies and Poppy Maidens, Barbara's little white linen slip and soft white sweater, and my grey business suit, were more conspicuous than would have been the Ahkoond of Swat and his Captive Slave. Even after the confetti had sprinkled her black hair until it reminded me of Skeet's blossom wreath, infinitely multiplied, I still saw the glances through the eye-holes of masks follow us wonderingly.

Opposite the city hall, where we must cross to get to the Capehart street, we were again almost stopped by the dense crowd. The Square was a green-turfed dancing floor; from its stand, an orchestra jazzed out the latest and dizziest of dances; and countless couples one-stepped on the gra.s.s, on the asphalt of the streets, even over the lawns of adjacent houses, tree trunks and flower beds adding more things to be dodged. At one corner, where the crowd was thick, we saw a big man being wound to a pole by paper serpentines. Yelling and capering, the masked dancers milled around and around him, winding the gay ribbons, while others with confetti and the Spanish cascarones, tried to snow him under. As we came up, a big fist wagged and Bill Capehart's voice roared,

"Hold on! Too much is a-plenty!"

He tore himself loose, streaming with paper strips, bent and filled his fists from the confetti at his feet. His tormentors howled and dropped back as much as they could for the hemming crowd; he rushed them, heaving paper ammunition in a hail-storm, and reached us in two or three jumps.

"Golly!" he roared, "Me for a cyclone cellar! This is a riot. You ain't in costume, either. Wonder they wouldn't pick on you."

With the words they did. I put Barbara behind me, and was conscious only of a blinding snow of paper flakes, the punch and slap of dusters, in an uproar of horns and bells.

"Good deal like fighting a swarm of bees in your shirt-tail with a willow switch," old Bill panted at my shoulder. "Gosh!" as the snapping of firecrackers let loose beneath our feet. "Some o' these mosquito-net skirts'll get afire next--then there'll be h.e.l.l a-popping!"

Close at hand there was a louder report, as of a giant cracker, and at that Barbara sagged against me. I whirled and put an arm about her.

Bill grabbed her from me, and lifted her above the pressure of the crowd. I charged ahead, shouting,

"Gangway! Let us through!"

Willing enough, the mob could not make room for pa.s.sage until my shoulder, lowered to strike at the breast, forced a way, that closed in the instant Bill gained through. It was football tactics, with me bucking the line, Bill carrying the ball. Fortunately, the bunch was a good-natured festival gathering, or my rough work might have brought us trouble. As it was, a short, stiff struggle took us to the outer fringe of the mob.

"How is she? What happened?" I grunted, coming to a stop.

"Search me." Bill twisted around to look at the white face that lay back on his shoulder, with closed lids. Three strokes chimed from the city hall tower. Barbara's eyes flashed open; as the last stroke trembled in the air, Barbara's voice came, sharp with breathless urgence,

"A quarter of ten! Quick--get me to the country club!"

"Take _you_ there? Now, d'ye mean?" I e.j.a.c.u.l.a.t.ed; and holding her like a baby, Bill's eyes flared into mine. "Did something happen to you back there, girl? Or did you just faint?"

"Never mind about me! There," that glance of hers that saw everything indicated a parking place packed with machines half a block away up a side street. "Carry me there. Take one of those cars. Get me to the country club. Don't--" as I opened my mouth, "don't ask questions."

I turned and ran. Bill galloped behind. Barbara had lifted her head to cry after me,

"The best one! Pick the fastest!"

I plunged down the line of cars, looking for a good machine and one with whose drive I was familiar. The guard rushed up to stop me; I showed him my badge, leaped into the front seat of a speed-built Tarpon, and had it out by the time Bill came up with the girl in his arms. I turned and swung open the tonneau door. Almost with one movement, he lifted her in and climbed after. I started off with braying horn, and at that I had to use caution. Making my way toward the corner of the street that led to Bill's house, I felt a small hand clutch the slack of my coat between the shoulders, and Barbara's voice, faint, but with a fury of determination in it, demanded,

"Where are you going? I said the country club."
