Herman had answered the question, but when I examined the answer I found it contained precious little. Perhaps it was indeed all he knew, for, although Garrick put several other questions to him and he answered quite readily and with apparent openness, there was very little more that we learned.

"Yes," concluded Herman, "someone cooked her, all right. They don't take long to square things with anyone who raps to the 'bulls.'"

"That's right," agreed Garrick. "And the underworld isn't alone in that feeling. No one likes a 'snitch.'"

"Bet your life," emphasized Herman heartily, then edging toward the door, he said, "Well, gentlemen, I'm glad to meet you and I'll work with you. I wish you success, all right. It's a hard case. Why, there wasn't any trace of a murder or violence in that place in which Rena Taylor must have been murdered. I suppose you have heard that there wasn't any bullet found in the body, either?"

"Yes," answered Garrick, "so far it does look inexplicable."

Inspector Herman withdrew. One could see that he had little faith in these "amateur" detectives.

A telephone message for Dillon about another departmental matter terminated our interview and we went our several ways.

"Much help I've ever got from a regular detective like Herman,"

remarked Garrick, phrasing my own idea of the matter, as we paid the fare of our cab a few minutes later and entered his office.

"Yes," I agreed. "Why, he's even stumped at the start by the mystery of there being no bullet. I'm glad you said nothing about the cartridge, although I can't see for the life of me what good it is to us."

I had ventured the remark, hoping to entice Garrick into talking. It worked, at least as far as Garrick wanted to talk yet.

"You'll see about the cartridge soon enough, Tom," he rejoined. "As for there being no bullet, there was a bullet--only it was of a kind you never dreamed of before."

He regarded me contemplatively for a moment, then leaned over and in a voice full of meaning, concluded, "That bullet was composed of something soft or liquid, probably confined in some kind of thin capsule. It mushroomed out like a dumdum bullet. It was deadly. But the chief advantage was that the heat that remained in Rena Taylor's body melted all evidence of the bullet. That was what caused that greasy, oleaginous appearance of the wound. The murderer thought he left no trail in the bullet in the corpse. In other words, it was practically a liquid bullet."

CHAPTER V

THE BLACKMAILER

It was late in the afternoon, while Garrick was still busy with a high-powered microscope, making innumerable micro-photographs, when the door of the office opened softly and a young lady entered.

As she advanced timidly to us, we could see that she was tall and gave promise of developing with years into a stately woman--a p.r.o.nounced brunette, with sparkling black eyes. I had not met her before, yet somehow I could not escape the feeling that she was familiar to me.

It was not until she spoke that I realized that it was the eyes, not the face, which I recognized.

"You are Mr. Garrick?" she asked of Guy in a soft, purring voice which, I felt, masked a woman who would fight to the end for anyone or anything she really loved.

Then, before Guy could answer, she explained, "I am Miss Violet Winslow. A friend of mine, Mr. Warrington, has told me that you are investigating a peculiar case for him--the strange loss of his car."

Garrick hastened to place a chair for her in the least cluttered and dusty part of the room. There she sat, looking up at him earnestly, a dainty contrast to the den in which Garrick was working out the capture of criminals, violent and vicious.

"I have the honor to be able to say, 'Yes' to all that you have asked, Miss Winslow," he replied. "Is there any way in which I can be of service to you?"

I thought a smile played over his face at the thought that perhaps she might have come to ask him to work for three clients instead of two.

At any rate, the girl was very much excited and very much in earnest, as she opened her handbag and drew from it a letter which she handed to Garrick.

"I received that letter," she explained, speaking rapidly, "in the noon mail to-day. I don't know what to make of it. It worries me to get such a thing. What do you suppose it was sent to me for? Who could have sent it?"

She was leaning forward artlessly on her crossed knee looking expectantly up into Garrick's face, oblivious to everything else, even her own enticing beauty. There was something so simple and sincere about Violet Winslow that one felt instinctively that nothing was too great a price to shield her from the sordid and the evil in the world.

Yet something had happened that had brought her already into the office of a detective.

Garrick had glanced quickly at the outside of the slit envelope. The postmark showed that it had been mailed early that morning at the general post office and that there was slight chance of tracing anything in that direction.

Then he opened it and read. The writing was in a bold scrawl and hastily executed:

You have heard, no doubt, of the alleged loss of an automobile by Mr.

Mortimer Warrington. I have seen your name mentioned in the society columns of the newspapers in connection with him several times lately.

Let a disinterested person whom you do not know warn you in time. There is more back of it than he will care to tell. I can say nothing of the nefarious uses to which that car has been put, but you will learn more shortly. Meanwhile, let me inform you that he and some of the wilder of his set had that night planned a visit to a gambling house on Forty-eighth Street. I myself saw the car standing before another gambling den on Forty-seventh Street about the same time. This place, I may as well inform you, bears an unsavory reputation as a gambling joint to which young ladies of the fastest character are admitted. If you will ask someone in whom you have confidence and whom you can ask to work secretly for you to look up the records, you will find that much of the property on these two blocks, and these two places in particular, belongs to the Warrington estate. Need I say more?

The letter was without superscription or date and was signed merely with the words, "A Well-Wisher." The innuendo of the thing was apparent.

"Of course," she remarked, as Garrick finished reading, and before he could speak, "I know there is something back of it. Some person is trying to injure Mortimer. Still---"

She did not finish the sentence. It was evident that the "well-wisher"

need not have said more in order to sow the seeds of doubt.

As I watched her narrowly, I fancied also that from her tone the newspapers had not been wholly wrong in mentioning their names together recently.

"I hadn't intended to say anything more than to explain how I got the letter," she went on wistfully. "I thought that perhaps you might be interested in it."

She paused and studied the toe of her dainty boot. "And, of course,"

she murmured, "I know that Mr. Warrington isn't dependent for his income on the rent that comes in from such places. But--but I wish just the same that it wasn't true. I tried to call him up about the letter, but he wasn't at the office of the Warrington estate, and no one seemed to know just where he was."

She kept her eyes downcast as though afraid to betray just what she felt.

"You will leave this with me?" asked Garrick, still scrutinizing the letter.

"Certainly," she replied. "That is what I brought it for. I thought it was only fair that he should know about it."

Garrick regarded her keenly for a moment. "I am sure, Miss Winslow," he said, "that Mr. Warrington will thank you for your frankness. More than that, I feel sure that you need have no cause to worry about the insinuations of this letter. Don't judge harshly until you have heard his side. There's a good deal of graft and vice talk flying around loose these days. Miss Winslow, you may depend on me to dig the truth out and not deceive you."

"Thank you so much," she said, as she rose to go; then, in a burst of confidence, added, "Of course, after all, I don't care so much about it myself--but, you know, my aunt--is so dreadfully prim and proper that she couldn't forgive a thing like this. She'd never let Mr. Warrington call on me again."

Violet stopped and bit her lip. She had evidently not intended to say as much as that. But having once said it, she did not seem to wish to recall the words, either.

"There, now," she smiled, "don't you even hint to him that that was one of the reasons I called."

Garrick had risen and was standing beside her, looking down earnestly into her upturned face.

"I think I understand, Miss Winslow," he said in a low voice, rapidly.

"I cannot tell you all--yet. But I can promise you that even if all were told--the truth, I mean--your faith in Warrington would be justified." He leaned over. "Trust me," he said simply.

As she placed her small hand in Garrick's, she looked up into his face, and with suppressed emotion, answered, "Thank you--I--I will."

Then, with a quick gathering of her skirts, she turned and almost fled from the room.
