"It's no use!" he exclaimed. Remembering himself, he added: "We'll try the next street."

But even as he spoke he leaped forward. Coming apparently from nowhere, something white sank through the semi-darkness and fell at his feet.

It struck the pavement directly in front of the middle one of the three houses. Ford fell upon it and clutched it in both hands. It was a woman's glove. Ford raced back to the piano.

"Once more," he cried, "play 'Dixie'!"

He shouted out the chorus exultantly, triumphantly. Had he spoken it in words, the message could not have carried more clearly.

Ford now believed he had found the house, found the woman, and was eager only to get rid of his companion and, in his own person, return to Sowell Street. But, lest the man might suspect there was in his actions something more serious than a practical joke, he forced himself to sing the new songs in three different streets. Then, pretending to tire of his prank, he paid the musician and left him. He was happy, exultant, tingling with excitement. Good-luck had been with him, and, hoping that Gerridge's might yet yield some clew to Pearsall, he returned there.

Calling up the London office of the REPUBLIC, he directed that one of his a.s.sistants, an English lad named Cuthbert, should at once join him at that hotel. Cuthbert was but just out of Oxford. He wished to become a writer of fiction, and, as a means of seeing many kinds of life at first hand, was in training as a "Pressman." His admiration for Ford amounted to almost hero-worship; and he regarded an "a.s.signment" with his chief as a joy and an honor. Full of enthusiasm, and as soon as a taxicab could bring him, he arrived at Gerridge's, where, in a corner of the deserted coffee-room, Ford explained the situation. Until he could devise a way to enter the Sowell Street house. Cuthbert was to watch over it.

"The number of the house is forty," Ford told him; "the name on the door-plate, Dr. Prothero. Find out everything you can about him without letting any one catch you at it. Better begin at the nearest chemist's.

Say you are on the verge of a nervous breakdown, and ask the man to mix you a sedative, and recommend a physician. Show him Prothero's name and address on a piece of paper, and say Prothero has been recommended to you as a specialist on nervous troubles. Ask what he thinks of him. Get him to talk. Then visit the trades-people and the public-houses in the neighborhood, and say you are from some West End shop where Prothero, wants to open an account. They may talk, especially if his credit is bad. And, if you find out enough about him to give me a working basis, I'll try to get into the house to-night. Meanwhile, I'm going to make another quick search of this hotel for Pearsall. I'm not satisfied he has not been here. For why should Miss Dale, with all the hotels in London to choose from, have named this particular one, unless she had good reason for it? Now, go, and meet me in an hour in Sowell Street."

Cuthbert was at the door when he remembered he had brought with him from the office Ford's mail and cablegrams. Among the latter was the one for which Ford had asked.

"Wait," he commanded. "This is about the girl. You had better know what it says." The cable read:

"Girl orphan, Dalesville named after her family, for three generations mill-owners, father died four years ago, Pearsall brother-in-law until she is twenty-one, which will be in three months. Girl well known, extremely popular, lived Dalesville until last year, when went abroad with uncle, since then reports of melancholia and nervous prostration, before that health excellent--no signs insanity--none in family. Be careful how handle Pearsall, was doctor, gave up practice to look after estate, is prominent in local business and church circles, best reputation, beware libel."

For the benefit of Cuthbert, Ford had been reading the cable aloud. The last paragraph seemed especially to interest him, and he read it twice, the second time slowly, and emphasizing the word "doctor."

"A doctor!" he repeated. "Do you see where that leads us? It may explain several things. The girl was in good health until went abroad with her uncle, and he is a medical man."

The eyes of Cuthbert grew wide with excitement.

"You mean poison!" he whispered. "Slow poison!"

"Beware libel," laughed Ford nervously, his own eyes lit with excitement. "Suppose," he exclaimed, "he has been using a.r.s.enic? He would have many opportunities, and it's colorless, tasteless; and a.r.s.enic would account for her depression and melancholia. The time when he must turn over her money is very near, and, suppose he has spent the money, speculated with it, and lost it, or that he still has it and wants to keep it? In three months she will be of age, and he must make an accounting. The a.r.s.enic does not work fast enough. So what does he do? To save himself from exposure, or to keep the money, he throws her into this private sanatorium, to make away with her."

Ford had been talking in an eager whisper. While he spoke his cigar had ceased to burn, and to light it, from a vase on the mantel he took a spill, one of those spirals of paper that in English hotels, where the proprietor is of a frugal mind, are still used to prevent extravagance in matches. Ford lit the spill at the coal fire, and with his cigar puffed at the flame. As he did so the paper unrolled. To the astonishment of Cuthbert, Ford clasped it in both hands, blotted out the tiny flame, and, turning quickly to a table, spread out the charred paper flat. After one quick glance, Ford ran to the fireplace, and, seizing a handfull of the spills, began rapidly to unroll them. Then he turned to Cuthbert and, without speaking, showed him the charred spill. It was a sc.r.a.p torn from the front page of a newspaper. The half-obliterated words at which Ford pointed were DALESVILLE COUR ----

"His torn paper!" said Ford. "The DALESVILLE COURIER. Pearsall HAS been in this hotel!" He handed another spill to Cuthbert.

"From that one," said Ford, "we get the date, December 3. Allowing three weeks for the newspaper to reach London, Pearsall must have seen it just three weeks ago, just when Miss Dale says he was in the hotel. The landlord has lied to me."

Ford rang for a waiter, and told him to ask Mr. Gerridge to come to the smoking-room.

As Cuthbert was leaving it, Gerridge was entering it, and Ford was saying:

"It seems you've been lying to the police and to me. Unless you desire to be an accessory to a murder, You had better talk quick!"

An hour later Ford pa.s.sed slowly through Sowell Street in a taxicab, and, finding Cuthbert on guard, signalled him to follow. In Wimpole Street the cab drew up to the curb, and Cuthbert entered it.

"I have found Pearsall," said Ford. "He is in No. 40 with Prothero."

He then related to Cuthbert what had happened. Gerridge had explained that when the Police called, his first thought was to protect the good name of his hotel. He had denied any knowledge of Pearsall only because he no longer was a guest, and, as he supposed Pearsall had pa.s.sed out of his life, he saw no reason, why, through an arrest and a scandal, his hotel should be involved. Believing Ford to be in the secret service of the police, he was now only too anxious to clear himself of suspicion by telling all he knew. It was but little. Pearsall and his niece had been at the hotel for three days. During that time the niece, who appeared to be an invalid, remained in her room. On the evening of the third day, while Pearsall was absent, a call from him had come for her by telephone, on receiving which Miss Dale had at once left the hotel, apparently in great agitation. That night she did not return, but in the morning Pearsall came to collect his and her luggage and to settle his account. He explained that a woman relative living at the Langham Hotel had been taken suddenly ill, and had sent for him and his niece. Her condition had been so serious that they had remained with her all night, and his niece still was at her bedside. The driver of a four-wheeler, who for years had stood on the cab-rank in front of Gerridge's, had driven Pearsall to the Langham. This man was at the moment on the rank, and from him Ford learned what he most wished to know.

The cabman remembered Pearsall, and having driven him to the Langham, for the reason that immediately after setting him down there, and while "crawling" for a fare in Portland Place, a whistle from the Langham had recalled him, and the same luggage that had just been taken from the top of his cab was Put back on it, and he was directed by the porter of the hotel to take it to a house in Sowell Street. There a man-servant had helped him unload the trunks and had paid him his fare. The cabman did not remember the number of the house, but knew it was on the west side of the street and in the middle of the block.

Having finished with Gerridge and the cab-man, Ford had at once gone to the Langham Hotel, where, as he antic.i.p.ated, nothing was known of Pearsall or his niece, or of any invalid lady. But the hall-porter remembered the American gentleman who had driven up with many pieces of luggage, and who, although it was out of season, and many suites in the hotel were vacant, had found none to suit him. He had then set forth on foot, having left word that his trunks be sent after him. The address he gave was a house in Sowell Street.

The porter recalled the incident because he and the cabman had grumbled over the fact that in five minutes they had twice to handle the same boxes.

"It is pretty evident," said Ford, what Pearsall had in mind, but chance was against him. He thought when he had unloaded his trunks at the Langham and dismissed the cabman he had destroyed the link connecting him with Gerridge's. He could not foresee that the same cabman would be loitering in the neighborhood. He should have known that four-wheelers are not as plentiful as they once were; and he should have given that particular one more time to get away. His idea in walking to the Sowell Street house was obviously to prevent the new cabman from seeing him enter it. But, just where he thought he was clever, was just where he tripped. If he had remained with his trunks he would have seen that the cabman was the same one who had brought them and him from Craven Street, and he would have given any other address in London than the one he did.

"And now," said Ford, "that we have Pearsall where we want him, tell me what you have learned about Prothero?"

Cuthbert smiled importantly, and produced a piece of paper scribbled over with notes.

"Prothero," he said, "seems to be THIS sort of man. If he made your coffee for you, before you tasted it, you'd like him to drink a cup of it first."

II

"Prothero," said Cuthbert, "is a man of mystery. As soon as I began asking his neighbors questions, I saw he was of interest and that I was of interest. I saw they did not believe I was an agent of a West End shop, but a detective. So they wouldn't talk at all, or else they talked freely. And from one of them, a chemist named Needham, I got all I wanted. He's had a lawsuit against Prothero, and hates him. Prothero got him to invest in a medicine to cure the cocaine habit. Needham found the cure was no cure, but cocaine disguised. He sued for his money, and during the trial the police brought in Prothero's record. Needham let me copy it, and it seems to embrace every crime except treason. The man is a Russian Jew. He was arrested and prosecuted in Warsaw, Vienna, Berlin, Belgrade; all over Europe, until finally the police drove him to America. There he was an editor of an anarchist paper, a blackmailer, a 'doctor' of hypnotism, a clairvoyant, and a professional bigamist. His game was to open rooms as a clairvoyant, and advise silly women how to invest their money. When he found out which of them had the most money, he would marry her, take over her fortune, and skip. In Chicago, he was tried for poisoning one wife, and the trial brought out the fact that two others had died under suspicious circ.u.mstances, and that there were three more unpoisoned but anxious to get back their money. He was sentenced to ten years for bigamy, but pardoned because he was supposed to be insane, and dying. Instead of dying, he opened a sanatorium in New York to cure victims of the drug habit. In reality, it was a sort of high-priced opium-den. The place was raided, and he jumped his bail and came to this country. Now he is running this private hospital in Sowell Street. Needham says it's a secret rendezvous for dope fiends. But they are very high-cla.s.s dope fiends, who are willing to pay for seclusion, and the police can't get at him. I may add that he's tall and muscular, with a big black beard, and hands that could strangle a bull. In Chicago, during the poison trial, the newspapers called him 'the Modern Bluebeard."'

For a short time Ford was silent. But, in the dark corner of the cab, Cuthbert could see that his cigar was burning briskly.

"Your friend seems a nice chap," said Ford at last. "Calling on him will be a real pleasure. I especially like what you say about his hands."

"I have a plan," began the a.s.sistant timidly, "a plan to get you into the house-if you don't mind my making suggestions?"

"Not at all!" exclaimed his chief heartily.

"Get me into the house by all means; that's what we're here for. The fact that I'm to be poisoned or strangled after I get there mustn't discourage us.'"

"I thought," said Cuthbert, "I might stand guard outside, while you got in as a dope fiend."

Ford snorted indignantly. "Do I LOOK like a dope fiend?" he protested.

The voice of the a.s.sistant was one of discouragement.

"You certainly do not," he exclaimed regretfully. "But it's the only plan I could think of."

"It seems to me," said his chief testily, "that you are not so very healthy-looking yourself. What's the matter with YOUR getting inside as a dope fiend and MY standing guard?"

"But I wouldn't know what to do after I got inside," complained the a.s.sistant, "and you would. You are so clever."

The expression of confidence seemed to flatter Ford.

"I might do this," he said. "I might pretend I was recovering from a heavy spree, and ask to be taken care of until I am sober. Or I could be a very good imitation of a man on the edge of a nervous breakdown.

I haven't been five years in the newspaper business without knowing all there is to know about nerves. That's it!" he cried. "I will do that!

And if Mr. Bluebeard Svengali, the Strangler of Paris person, won't take me in as a patient, we'll come back with a couple of axes and BREAK in.

But we'll try the nervous breakdown first, and we'll try it now. I will be a naval officer," declared Ford. "I made the round-the-world cruise with our fleet as a correspondent, and I know enough sea slang to fool a medical man. I am a naval officer whose nerves have gone wrong. I have heard of his sanatorium through----" "How," asked Ford sharply, "have I heard of his sanatorium?"
