"I guess Sheridan'll know you fast enough when he sees you. Come on, boys!" He opened the door and led the way across the sidewalk to the patrol wagon, which stood backed against the curb.
It was a glorious winter's day. The sharp, frosty air stimulated the clubman's jaded senses and gave him new hope; he felt sure that at headquarters he would find some person to whom he could safely confide the secret of his identity. In about ten minutes the wagon stopped in a narrow street, before an inhospitable-looking building.
"Here's the old place," remarked one of the load cheerfully. "Looks just the same as ever. Mott Street's not a mite different. And to think I ain't been here in fifteen years!"
All clambered out, and each officer, selecting his prisoners, convoyed them down a flight of steps, through a door, several feet below the level of the sidewalk, and into a small, stuffy chamber full of men smoking and lounging. Most of these seemed to take a friendly interest in the clubman, a few accosting him by his now familiar alias.
Tom hurried McAllister along a dark corridor, out into a cold court-yard, across the cobblestones into another door, through a hall lighted only by a dim gas-jet, and then up a flight of winding stairs. McAllister's head whirled. Then quickly they were at the top, and in a huge, high-ceiled room crowded with men in civilian dress. On one side, upon a platform, stood a nondescript row of prisoners, at whom the throng upon the floor gazed in silence. Above the heads of this file of motley individuals could be read the gold lettering upon the cabinet behind them—Rogues' Gallery. On the other side of the room, likewise upon a platform and behind a long desk, stood two officers in uniform, one of them an inspector, engaged in studying with the keenest attention the human exhibition opposite.
"Get up there, Fatty!"
Before he realized what had happened, McAllister was pushed upon the platform at the end of the line. His appearance created a little wave of excitement, which increased when his comrades of the wagon joined him. It was a peculiar scene. Twenty men standing up for inspection, some gazing unconcernedly before them, some glaring defiantly at their observers, and others grinning recognition at familiar faces. McAllister grew cold with fright. Several of the detectives pointed at him and nodded. Out of the silence the Inspector's voice came with the shock of thunder:
"Hey, there, you, Sanders, hold up your hand!"
A short man near the head of the line lifted his arm.
"Take off your hat."
The prisoner removed his head-gear with his other hand. The Inspector raised his voice and addressed the crowd of detectives, who turned with one accord to examine the subject of his discourse.
"That's Biff Sanders, con man and all-round thief. Served two terms up the river for grand larceny—last time an eight-year bit; that was nine years ago. Take a good look at him. I want you to remember his face. Put your hat on."
Sanders resumed his original position, his face expressing the most complete indifference.
A slight, good-looking young man now joined the Inspector and directed his attention to the prisoner next the clubman, the same being he who had remarked upon the familiar appearance of Mott Street.
"Hold up your hand!" ordered the Inspector. "You're Muggins, aren't you? Haven't been here in fifteen years, have you?"
The man smiled.
"You're right, Inspector," he said. "The last time was in '89."
"That's Muggins, burglar and sneak; served four terms here, and then got settled for life in Louisville for murder. Pardoned after he'd served four years. Look at him."
Thus the curious proceeding continued, each man in the line being inspected, recognized, and his record and character described by the Inspector to the assembled bureau of detectives. No other voice was heard save the harsh tones of some prisoner in reply.
Then the Inspector looked at McAllister.
"Welch, hold up your hand."
McAllister shuddered. If he refused, he knew not what might happen to him. He had heard of the horrors of the "Third Degree," and associated it with starvation, the rack, and all kinds of brutality. They might set upon him in a body. He might be mobbed, beaten, strangled. And yet, if he obeyed, would it not be a public admission that he was the mysterious and elusive Welch? Would it not bind the chains more firmly about him and render explanation all the more difficult?
"Do you hear? Hold up your hand, and be quick about it!"
His hand went up of its own accord.
The Inspector cleared his throat and rapped upon the railing.
"Take a good look at this man. He's Fatty Welch, one of the cleverest thieves in the country. Does a little of everything. Began as a valet to a clubman in this city. He got settled for stealing a valuable pin about three years ago, and served a short term up the river. Since then he's been all over. His game is to secure employment in fashionable houses as butler or servant and then get away with the jewelry. He's wanted for a big job down in Pennsylvania. Take a good look at him. When he gets out we don't want him around these parts. I'd like you precinct-men to remember him."
The detectives crowded near to get a close view of the interesting criminal. One or two of them made notes in memorandum books. The slender man had a hasty conference with the Inspector.
"The officer who has Welch, take him up to the gallery and then bring him down to the record room," directed the Inspector.
"Get down, Fatty!" commanded Tom. McAllister, stupefied with horror, embarrassment, and apprehension of the possibilities in store for him, stepped down and followed like a somnambulist. As they made their way to the elevator he could hear the strident voice of the Inspector beginning again:
"This is Pat Hogan, otherwise known as 'Paddy the Sneak,' and his side partner, Jim Hawkins, who goes under the name of James Hawkinson. His pals call him 'Supple Jim.' Two of the cleverest sneaks in the country. They branch out into strong arm work occasionally."
The elevator began to ascend.
"You seem kinder down," commented Tom. "I suppose you expect to get settled for quite a bit down to Philadelphia, eh? Well, don't talk unless you feel like it. Here we are!"
They got out upon an upper floor and crossed the hall. On their left a matron was arranging rows of tiny chairs in a small school-room or nursery. At any other time the Lost Children's Room might have aroused a flicker of interest in McAllister, but he felt none whatever in it now. Tom opened a door and pushed the clubman gently into a small, low-ceiled chamber. Charts and diagrams of the human cranium hung on one wall, while a score of painted eyes, each of a different color, and each bearing a technical appellation and a number, stared from the other. Upon a small square platform, about eight inches in height, stood a half-clad Italian congealed with terror and expecting momentarily to receive a shock of electricity. The slender young man was rapidly measuring his hands and feet and calling out the various dimensions to an assistant, who recorded them upon a card. This accomplished, he ordered his victim down from the block, seated him unceremoniously in a chair, and with a pair of shining instruments gauged the depth of his skull from front to rear, its width between the cheekbones, and the length of the ears, describing all the while the other features in brief terms to his associate.
"Now off with you!" he ejaculated. "Here, lug this Greaser in and mug him."
The officer in the case haled the Italian,
