"And the letter was for Mr. Fitzgerald?"

"Yes, sir; and a precious dirty letter it was, too."

"You gave it to him, of course?"

"I did, sir. He was playing cards, and he put it in his pocket, after having looked at the outside of it, and went on with his game."

"Didn't he open it?"

"Not then, sir; but he did later on, about a quarter to one o'clock. I was in the room, and he opens it and reads it. Then he says to himself, 'What d--d impertinence,' and puts it into his pocket."

"Was he disturbed!"

"Well, sir, he looked angry like, and put his coat and hat on, and walked out about five minutes to one."

"Ah! and he met Whyte at one," muttered Calton. "There's no doubt about it. The letter was an appointment, and he was going to keep it. What kind of a letter was it?" he asked.

"Very dirty, sir, in a square envelope; but the paper was good, and so was the writing."

"That will do," said Calton; "I am much obliged to you," and he hurried down to where Madge awaited him in the cab.

"You were right," he said to her, when the cab was once more in motion.

"He got a letter on that night, and went to keep his appointment at the time he met Whyte."

"I knew it," cried Madge with delight. "You see, we will find it in his lodgings."

"I hope so," answered Calton; "but we must not be too sanguine; he may have destroyed it."

"No, he has not," she replied. "I am convinced it is there."

"Well," answered Calton, looking at her, "I don't contradict you, for your feminine instincts have done more to discover the truth than my reasonings; but that is often the case with women--they jump in the dark where a man would hesitate, and in nine cases out of ten land safely."

"Alas for the tenth!" said Miss Frettlby. "She has to be the one exception to prove the rule."

She had in a great measure recovered her spirits, and seemed confident that she would save her lover. But Mr. Calton saw that her nerves were strung up to the highest pitch, and that it was only her strong will that kept her from breaking down altogether.

"By Jove," he muttered, in an admiring tone, as he watched her. "She's a plucky girl, and Fitzgerald is a lucky man to have the love of such a woman."

They soon arrived at Brian's lodgings, and the door was opened by Mrs.

Sampson, who looked very disconsolate indeed. The poor cricket had been blaming herself severely for the information she had given to the false insurance agent, and the floods of tears which she had wept had apparently had an effect on her physical condition, for she crackled less loudly than usual, though her voice was as shrill as ever.

"That sich a thing should 'ave 'appened to 'im," she wailed, in her thin, high voice. "An' me that proud of 'im, not 'avin' any family of my own, except one as died and went up to 'eaving arter 'is father, which I 'opes as they both are now angels, an' friendly, as 'is nature 'ad not developed in this valley of the shadder to determine 'is feelin's towards is father when 'e died, bein' carried off by a chill, caused by the change from 'ot to cold, the weather bein' that contrary."

They had arrived in Brian's sitting-room by this time, and Madge sank into a chair, while Calton, anxious to begin the search, hinted to Mrs.

Sampson that she could go.

"I'm departin', sir," piped the cricket, with a sad shake of her head, as she opened the door; "knowin', as I do, as 'e's as innocent as an unborn babe, an' to think of me 'avin' told that 'orrid pusson who 'ad no regard for the truth all about 'im as is now in a cold cell, not as what the weather ain't warm, an' 'e won't want a fire as long as they allows 'im blankets."

"What did you tell him?" asked Calton, sharply.

"Ah! you may well say that," lamented Mrs. Sampson, rolling her dingy handkerchief into a ball, and dabbing at her red-rimmed eyes, which presented quite a baccha.n.a.lian appearance, due, be it said in justice, to grief, not to liquor. "'Avin' bin beguiled by that serping in light clothes as wanted to know if 'e allays come 'ome afore twelve, which I said 'e was in the 'abit of doin', tho', to be sure, 'e did sometimes use 'is latch-key."

"The night of the murder, for instance."

"Oh! don't say that, sir," said Mrs. Sampson, with a terrified crackle.

"Me bein' weak an' ailin', tho' comin' of a strong family, as allays lived to a good age, thro' bein' in the 'abit of wearin' flannels, which my mother's father thought better nor a-spilin' the inside with chemistry."

"Clever man, that detective," murmured Calton to himself. "He got out of her by strategy what he never would have done by force. It's a strong piece of evidence against Fitzgerald, but it does not matter much if he can prove an ALIBI. You'll likely be called as a witness for the prosecution," he said aloud.

"Me, sir!" squeaked Mrs. Sampson, trembling violently, and thereby producing a subdued rustle, as of wind in the trees. "As I've never bin in the court, 'cept the time as father tooked me for a treat, to 'ear a murder, which there's no denyin' is as good as a play, 'e bein' 'ung, 'avin' 'it 'is wife over the 'ead with the poker when she weren't lookin', and a-berryin' 'er corpse in a back garding, without even a stone to mark the place, let alone a line from the Psalms and a remuneration of 'er virtues."

"Well, well," said Calton, rather impatiently, as he opened the door for her, "leave us for a short time, there's a good soul. Miss Frettlby and I want to rest, and we will ring for you when we are going."

"Thank you, sir," said the lachrymose landlady, "an' I 'opes they won't 'ang 'im, which is sich a choky way of dyin'; but in life we are in death," she went on, rather incoherently, "as is well known to them as 'as diseases, an' may be corpsed at any minute, and as--"

Here Calton, unable to restrain his impatience any longer, shut the door, and they heard Mrs. Sampson's shrill voice and subdued cracklings die away in the distance.

"Now then," he said, "now that we have got rid of that woman and her tongue, where are we to begin?"

"The desk," replied Madge, going over to it. "It's the most likely place."

"Don't think so," said Calton, shaking his head. "If, as you say, Fitzgerald is a careless man, he would not have troubled to put it there. However; perhaps we'd better look."

The desk was very untidy ("Just like Brian," as Madge remarked)--full of paid and unpaid bills, old letters, play-bills, ball-programmes, and withered flowers.

"Reminiscences of former flirtations," said Calton, with a laugh, pointing to these.

"I should not wonder," retorted Miss Frettlby, coolly. "Brian always was in love with some one or other; but you know what Lytton says, 'There are many counterfeits, but only one Eros,' so I can afford to forget these things."

The letter, however, was not to be found in the desk, nor was it in the sitting-room. They tried the bedroom, but with no better result. Madge was about to give up the search in despair, when suddenly Calton's eye fell on the waste-paper basket, which, by some unaccountable reason, they had over-looked. The basket was half-full, in fact; more than half, and, on looking at it, a sudden thought struck the lawyer. He rang the bell, and presently Mrs. Sampson made her appearance.

"How long has that waste-paper basket been standing like that?" he asked, pointing to it.

"It bein' the only fault I 'ad to find with 'im," said Mrs. Sampson, "'e bein' that untidy that 'e a never let me clean it out until 'e told me pussonly. 'E said as 'ow 'e throwed things into it as 'e might 'ave to look up again; an' I 'aven't touched it for more nor six weeks, 'opin' you won't think me a bad 'ousekeeper, it bein' 'is own wish--bein' fond of litter an' sich like."

"Six weeks," repeated Calton, with a look at Madge. "Ah, and he got the letter four weeks ago. Depend upon it, we shall find it there."

Madge gave a cry, and falling on her knees, emptied the basket out on the floor, and both she and Calton were soon as busy among the fragments of paper as though they were rag-pickers.

"'Opin they ain't orf their 'eads," murmured Mrs. Sampson, as she went to the door, "but it looks like it, they bein'--"

Suddenly a cry broke from Madge, as she drew out of the ma.s.s of paper a half-burnt letter, written on thick and creamy-looking paper.

"At last," she cried, rising off her knees, and smoothing it out; "I knew he had not destroyed it."

"Pretty nearly, however," said Calton, as his eye glanced rapidly over it; "it's almost useless as it is. There's no name to it."
