"Say, this here, now, bookseller guy must have struck it rich."

"Who, Mifflin?"

"Yeh; did ya see that car in front of his place this morning?"

"No."

"Believe me, some boat."

"Musta hired it, hey? Where'd he go at?"

"I didn't see. I just saw the bus standing front the door."

"Say, did you see that swell dame he's got clerking for him?"

"I sure did. What's he doing, taking her joy-riding?"

"Shouldn't wonder. I wouldn't blame him----"

Aubrey gave no sign of having heard, but got up and left the lunchroom.

Had the girl been kidnapped while he overslept? He burned with shame to think what a pitiful failure his knight-errantry had been. His first idea was to beard Weintraub and compel him to explain his connection with the bookshop. His next thought was to call up Mr.

Chapman and warn him of what had been going on. Then he decided it would be futile to do either of these before he really knew what had happened. He determined to get into the bookshop itself, and burst open its sinister secret.

He walked hurriedly round to the rear alley, and surveyed the domestic apartments of the shop. Two windows in the second storey stood slightly open, but he could discern no signs of life. The back gate was still unlocked, and he walked boldly into the yard.

The little enclosure was serene in the pale winter sunlight. Along one fence ran a line of bushes and perennials, their roots wrapped in straw. The gra.s.s plot was lumpy, the sod withered to a tawny yellow and granulated with a sprinkle of frost. Below the kitchen door--which stood at the head of a flight of steps--was a little grape arbour with a rustic bench where Roger used to smoke his pipe on summer evenings.

At the back of this arbour was the cellar door. Aubrey tried it, and found it locked.

He was in no mood to stick at trifles. He was determined to unriddle the mystery of the bookshop. At the right of the door was a low window, level with the brick pavement. Through the dusty pane he could see it was fastened only by a hook on the inside. He thrust his heel through the pane. As the gla.s.s tinkled onto the cellar floor he heard a low growl. He unhooked the catch, lifted the frame of the broken window, and looked in. There was Bock, with head quizzically tilted, uttering a rumbling guttural vibration that seemed to proceed automatically from his interior.

Aubrey was a little dashed, but he said cheerily "Hullo, Bock! Good old man! Well, well, nice old fellow!" To his surprise, Bock recognized him as a friend and wagged his tail slightly, but still continued to growl.

"I wish dogs weren't such sticklers for form," thought Aubrey. "Now if I went in by the front door, Bock wouldn't say anything. It's just because he sees me coming in this way that he's annoyed. Well, I'll have to take a chance."

He thrust his legs in through the window, carefully holding up the sash with its jagged triangles of gla.s.s. It will never be known how severely Bock was tempted by the extremities thus exposed to him, but he was an old dog and his martial instincts had been undermined by years of kindness. Moreover, he remembered Aubrey perfectly well, and the smell of his trousers did not seem at all hostile. So he contented himself with a small grumbling of protest. He was an Irish terrier, but there was nothing Sinn Fein about him.

Aubrey dropped to the floor, and patted the dog, thanking his good fortune. He glanced about the cellar as though expecting to find some lurking horror. Nothing more appalling than several cases of beer bottles met his eyes. He started quietly to go up the cellar stairs, and Bock, evidently consumed with legitimate curiosity, kept at his heels.

"Look here," thought Aubrey. "I don't want the dog following me all through the house. If I touch anything he'll probably take a hunk out of my shin."

He unlocked the door into the yard, and Bock obeying the Irish terrier's natural impulse to get into the open air, ran outside.

Aubrey quickly closed the door again. Bock's face appeared at the broken window, looking in with so quaint an expression of indignant surprise that Aubrey almost laughed. "There, old man," he said, "it's all right. I'm just going to look around a bit."

He ascended the stairs on tiptoe and found himself in the kitchen. All was quiet. An alarm clock ticked with a stumbling, headlong hurry.

Pots of geraniums stood on the window sill. The range, with its lids off and the fire carefully nourished, radiated a mild warmth. Through a dark little pantry he entered the dining room. Still no sign of anything amiss. A pot of white heather stood on the table, and a corncob pipe lay on the sideboard. "This is the most innocent-looking kidnapper's den I ever heard of," he thought. "Any moving-picture director would be ashamed not to provide a better stage-set."

At that instant he heard footsteps overhead. Curiously soft, m.u.f.fled footsteps. Instantly he was on the alert. Now he would know the worst.

A window upstairs was thrown open. "Bock, what are you doing in the yard?" floated a voice--a very clear, imperious voice that somehow made him think of the thin ringing of a fine gla.s.s tumbler. It was t.i.tania.

He stood aghast. Then he heard a door open, and steps on the stair.

Merciful heaven, the girl must not find him here. What WOULD she think? He skipped back into the pantry, and shrank into a corner. He heard the footfalls reach the bottom of the stairs. There was a door into the kitchen from the central hall: it was not necessary for her to pa.s.s through the pantry, he thought. He heard her enter the kitchen.

In his anxiety he crouched down beneath the sink, and his foot, bent beneath him, touched a large tin tray leaning against the wall. It fell over with a terrible clang.

"Bock!" said t.i.tania sharply, "what are you doing?"

Aubrey was wondering miserably whether he ought to counterfeit a bark, but it was too late to do anything. The pantry door opened, and t.i.tania looked in.

They gazed at each other for several seconds in mutual horror. Even in his abas.e.m.e.nt, crouching under a shelf in the corner, Aubrey's stricken senses told him that he had never seen so fair a spectacle. t.i.tania wore a blue kimono and a curious fragile lacy bonnet which he did not understand. Her dark, gold-spangled hair came down in two thick braids across her shoulders. Her blue eyes were very much alive with amazement and alarm which rapidly changed into anger.

"Mr. Gilbert!" she cried. For an instant he thought she was going to laugh. Then a new expression came into her face. Without another word she turned and fled. He heard her run upstairs. A door banged, and was locked. A window was hastily closed. Again all was silent.

Stupefied with chagrin, he rose from his cramped position. What on earth was he to do? How could he explain? He stood by the pantry sink in painful indecision. Should he slink out of the house? No, he couldn't do that without attempting to explain. And he was still convinced that some strange peril hung about this place. He must put t.i.tania on her guard, no matter how embarra.s.sing it proved. If only she hadn't been wearing a kimono--how much easier it would have been.

He stepped out into the hall, and stood at the bottom of the stairs in the throes of doubt. After waiting some time in silence he cleared the huskiness from his throat and called out:

"Miss Chapman!"

There was no answer, but he heard light, rapid movements above.

"Miss Chapman!" he called again.

He heard the door opened, and clear words edged with frost came downward. This time he thought of a thin tumbler with ice in it.

"Mr. Gilbert!"

"Yes?" he said miserably.

"Will you please call me a taxi?"

Something in the calm, mandatory tone nettled him. After all, he had acted in pure good faith.

"With pleasure," he said, "but not until I have told you something.

It's very important. I beg your pardon most awfully for frightening you, but it's really very urgent."

There was a brief silence. Then she said:

"Brooklyn's a queer place. Wait a few minutes, please."

Aubrey stood absently fingering the pattern on the wallpaper. He suddenly experienced a great craving for a pipe, but felt that the etiquette of the situation hardly permitted him to smoke.

In a few moments t.i.tania appeared at the head of the stairs in her customary garb. She sat down on the landing. Aubrey felt that everything was as bad as it could possibly be. If he could have seen her face his embarra.s.sment would at least have had some compensation.

But the light from a stair window shone behind her, and her features were in shadow. She sat clasping her hands round her knees. The light fell crosswise down the stairway, and he could see only a gleam of brightness upon her ankle. His mind unconsciously followed its beaten paths. "What a corking pose for a silk stocking ad!" he thought.

"Wouldn't it make a stunning full-page layout. I must suggest it to the Ankleshimmer people."

"Well?" she said. Then she could not refrain from laughter, he looked so hapless. She burst into an engaging trill. "Why don't you light your pipe?" she said. "You look as doleful as the Kaiser."

"Miss Chapman," he said, "I'm afraid you think--I don't know what you must think. But I broke in here this morning because I--well, I don't think this is a safe place for you to be."
