The detective slid his back down until only his hip pockets were resting on the polished leather surface of the chair. Then he spun around, lurched to his feet and straightened his long legs and neck, squaring shoulders which were inclined to slump slightly forward. "Okay, Perry," he said, "I'm on my way."

At the corridor door the detective turned and said to Mason, "Suppose I find out this fellow is a phoney, are you going to show him up?"

"Not me," Mason said, grinning. "I'll string him along and see what's back of the impersonation."

"Bet you even money he's a phoney," Drake said.

"His face looks honest," Mason asserted.

"Most bunco men's do," Drake told him. "That's why they make good in the racket."

"Well," Mason said dryly, "it's not too highly improbable that a real bishop should have an honest face. Get the hell out of here and get to work."

Drake stood still in the doorway. "You're not taking my bet, eh, Perry?" Mason reached quickly for a law book, as though intending to use it as a missile, and the detective hastily slammed the door shut.

The telephone rang. Mason answered it and heard Della Street 's voice saying, "Chief, there's a taxi driver out here. I think I'd better bring him in and let him talk to you."

"A taxi driver?"

"Yes."

"What the devil does he want?"

"Money," she said.

"And you think I should see him?"

"Yes."

"Can you tell me what it's about over the telephone?"

"I don't think I'd better."

"You mean he's where he can hear what you're saying?"

"Yes."

Mason said, "Okay, bring him in." He had hardly hung up the telephone receiver when the door from the outer office opened, and Della Street ushered an apologetic but insistent cab driver into the office.

"This man drove Bishop Mallory to the office, Chief," she said.

The cab driver nodded and said, "He asked me to wait out in front of the building. I'm in a loading zone and a cop boots me out. I find a parking place and roost there and don't see anything of my man. My meter's clocking up time, so I asked the elevator starter. It happens the starter remembers him. He says the guy asked for your office, so here I am. He's a stocky chap with a turned-round collar, around fifty or fifty-five."

Mason's voice showed no interest. "He hasn't left the building?"

"I haven't seen him come out and I've been watching, and the elevator starter says he hasn't come out because he remembered him. I've got three eighty-five on my meter and I wanna know where it's coming from."

"Where'd you pick this chap up?" Mason asked. The cab driver hesitated. Mason pulled a roll of bills from his pocket, pulled off a five and said with a grin, "I just wanted to protect myself by getting the information before advancing the money to cover the cab bill."

The cab driver said, "I picked him up at the Regal Hotel."

"And drove him directly here?"

"That's right."

"Was he in a hurry?"

"Plenty."

Mason passed over the bill and said, "I don't think there's any use waiting any longer."

"Not the way that cop's bawling me out, there isn't," the driver said, handing Mason the change, "and I just want to say this is damn white of you, governor. I've heard of you from the boys. You're a square shooter who gives a working man the breaks. If there's ever anything I can do for you, don't hesitate to say so. The name's Winters, Jack Winters."

"Fine, Jack," Mason said. "Perhaps someday I'll get you on a jury, and in the meantime your fare would doubtless give you a tip, so keep the change and buy yourself a cigar."

The man made a grinning exit.

Mason picked up the telephone, called Paul Drake and said, "Paul, start your men working on the Regal Hotel. He may be registered there as William Mallory. Call me back just as soon as you get him located, and be sure to tail everyone who contacts him."

Della Street, a model of slim efficiency in a close-fitting gray tailored suit, said, " Jackson would like to talk with you about the traction case, if you can spare a minute."

Mason nodded and said, "Send him in."

A moment later he was closeted with his law clerk, outlining the position which the respondent should take on an appeal from a large verdict in a personal injury case. From time to time, Della Street came and went, bustling about the office, cleaning up odds and ends of routine matters, as she always did before Mason became absorbed in an important case which was destined to occupy all of his time.

Mason was pointing out to his clerk the fallacy of the position assumed by the appellant in its opening brief, when Della Street entered the office to say, "Paul Drake on the line, Chief. He says it's important."

Mason nodded, picked up the telephone and heard Drake's voice speaking rapidly, with the drawl completely absent: "Perry, I'm over at the Regal Hotel, and I think you'd better come over right away if you're interested in that bishop of yours."

"Coming right now," Mason said, reaching for his hat as he hung up the telephone. "You needn't stay, Della," he told her, looking at his watch. "I'll call you at your apartment if there's anything I want. Jackson, go ahead and work out the brief along those lines and let me look it over before you file it." He rushed out into the corridor and caught a cab at the curb in front of the building. It took him less than fifteen minutes to reach the Regal Hotel, where Drake was waiting in the lobby, accompanied by a thick-necked, bald-headed individual with sneering eyes, who held the soggy end of a black cigar clamped between thick, pendulous lips.

"Shake hands with Jim Pauley, the house detective here," Drake said to Perry Mason.

Pauley said, "Howdydo, Mason," and shook hands, his eyes seeming to take a professional interest in Mason's features.

"Pauley's an old pal of mine," Drake said, closing one of his eyes in a slowly surreptitious wink, "one of the ablest detectives in the game. I tried to hire him a couple of times but didn't have money enough. He's got a level head on his shoulders and has given me several tips that have worked out. He's a good man to remember, Perry. He might help you a lot sometime with some of your cases."

Pauley shifted the cigar and said deprecatingly, "Aw, I ain't no genius. I just use common sense."

Drake's hand rested on the house detective's shoulder. "That's the way he is, Perry-modest. You'd never think he was the chap that caught the Easops, the slickest bunch of passkey thieves that ever worked the hotels. Of course, the police took all the credit, but it was Jim here who really did the job… Well, we've uncovered something, Perry-that is, Jim has. I guess you'd better tell him, Jim."

The house detective raised thick fingers to pull the soggy cigar from his mouth, as he said importantly, lowering his voice and looking about him as though fearful lest he should be overheard: "You know, we've got a William Mallory staying here and he's a queer one. He left here to go someplace in a taxi, and I noticed someone was tailing him in another cab. An ordinary man wouldn't have noticed it, but that's my business. I'm trained to that stuff, and I spotted the guy in a minute when he pulled away from the curb. I seen him speak to his driver and nod toward the cab Mallory was riding in, and I didn't need to hear what was said. He could just as well have put it in writing for me, so I sort of made up my mind I'd keep an eye on this guy, Mallory, because his tail might be anything from a private dick to a G-man. We're running a nice hotel here, gents, and we don't want the class of trade that carries a tail. So I decided I'd have a talk with this chap when he got back, and tell him we wanted his room.

"Well, when he came back there was a red-headed dame sitting in the lobby. She got up as soon as she got her lamps on him and flashed him the high-sign. He gave her a half a nod and then went right to the elevator. He has a funny way of walking. His legs are short, and he just pounds along with 'em at a mile-a-minute clip.
