was the last of them?" said the latter; and as the porter nodded sulkily, he asked: "Should you recognize the note that the Italian gave you?"
"I should," answered the porter with frosty dignity.
The inspector bustled out of the room, and returned a minute later with a letter-case in his hand.
"This was in his breast-pocket," said he, laying the bulging case on the table, and drawing up a chair. "Now, here are three letters tied together. Ah! this will be the one." He untied the tape, and held out a dirty envelope addressed in a sprawling, illiterate hand to "Mr. Hartridge, Esq." "Is that the note the Italian gave you?"
The porter examined it critically. "Yes," said he; "that is the one."
The inspector drew the letter out of the envelope, and, as he opened it, his eyebrows went up.
"What do you make of that, Doctor?" he said, handing the sheet to Thorndyke.
Thorndyke regarded it for a while in silence, with deep attention. Then he carried it to the window, and, taking his lens from his pocket, examined the paper closely, first with the low power, and then with the highly magnifying Coddington attachment.
"I should have thought you could see that with the naked eye," said the inspector, with a sly grin at me. "It's a pretty bold design."
"Yes," replied Thorndyke; "a very interesting production. What do you say, Mr. Marchmont?"
The solicitor took the note, and I looked over his shoulder. It was certainly a curious production. Written in red ink, on the commonest notepaper, and in the same sprawling hand as the address, was the following message: "You are given six days to do what is just. By the sign above, know what to expect if you fail." The sign referred to was a skull and crossbones, very neatly, but rather unskilfully, drawn at the top of the paper.
"This," said Mr. Marchmont, handing the document to Mr. Curtis, "explains the singular letter that he wrote yesterday. You have it with you, I think?"
"Yes," replied Mr. Curtis; "here it is."
He produced a letter from his pocket, and read aloud:
"'Yes: come if you like, though it is an ungodly hour. Your threatening letters have caused me great amusement. They are worthy of Sadler's Wells in its prime.
"'ALFRED HARTRIDGE.'"
"Was Mr. Hartridge ever in Italy?" asked Inspector Badger.
"Oh yes," replied Mr. Curtis. "He stayed at Capri nearly the whole of last year."
"Why, then, that gives us our clue. Look here. Here are these two other letters; E.C. postmark—Saffron Hill is E.C. And just look at that!"
He spread out the last of the mysterious letters, and we saw that, besides the memento mori, it contained only three words: "Beware! Remember Capri!"
"If you have finished, Doctor, I'll be off and have a look round Little Italy. Those four Italians oughtn't to be difficult to find, and we've got the porter here to identify them."
"Before you go," said Thorndyke, "there are two little matters that I should like to settle. One is the dagger: it is in your pocket, I think. May I have a look at it?"
The inspector rather reluctantly produced the dagger and handed it to my colleague.
"A very singular weapon, this," said Thorndyke, regarding the dagger thoughtfully, and turning it about to view its different parts. "Singular both in shape and material. I have never seen an aluminium hilt before, and bookbinder's morocco is a little unusual."
"The aluminium was for lightness," explained the inspector, "and it was made narrow to carry up the sleeve, I expect."
"Perhaps so," said Thorndyke.
He continued his examination, and presently, to the inspector's delight, brought forth his pocket lens.
"I never saw such a man!" exclaimed the jocose detective. "His motto ought to be, 'We magnify thee.' I suppose he'll measure it next."
The inspector was not mistaken. Having made a rough sketch of the weapon on his block, Thorndyke produced from his bag a folding rule and a delicate calliper-gauge. With these instruments he proceeded, with extraordinary care and precision, to take the dimensions of the various parts of the dagger, entering each measurement in its place on the sketch, with a few brief, descriptive details.
"The other matter," said he at length, handing the dagger back to the inspector, "refers to the houses opposite."
He walked to the window, and looked out at the backs of a row of tall buildings similar to the one we were in. They were about thirty yards distant, and were separated from us by a piece of ground, planted with shrubs and intersected by gravel paths.
"If any of those rooms were occupied last night," continued Thorndyke, "we might obtain an actual eyewitness of the crime. This room was brilliantly lighted, and all the blinds were up, so that an observer at any of those windows could see right into the room, and very distinctly, too. It might be worth inquiring into."
"Yes, that's true," said the inspector; "though I expect, if any of them have seen anything, they will come forward quick enough when they read the report in the papers. But I must be off now, and I shall have to lock you out of the rooms."
As we went down the stairs, Mr. Marchmont announced his intention of calling on us in the evening, "unless," he added, "you want any information from me now."
"I do," said Thorndyke. "I want to know who is interested in this man's death."
"That," replied Marchmont, "is rather a queer story. Let us take a turn in that garden that we saw from the window. We shall be quite private there."
He beckoned to Mr. Curtis, and, when the inspector had departed with the police-surgeon, we induced the porter to let us into the garden.
"The question that you asked," Mr. Marchmont began, looking up curiously at the tall houses opposite, "is very simply answered. The only person immediately interested in the death of Alfred Hartridge is his executor and sole legatee, a man named Leonard Wolfe. He is no relation of the deceased, merely a friend, but he inherits the entire estate—about twenty thousand pounds. The circumstances are these: Alfred Hartridge was the elder of two brothers, of whom the younger, Charles, died before his father, leaving a widow and three children. Fifteen years ago the father died, leaving the whole of his property to Alfred, with the understanding that he should support his brother's family and make the children his heirs."
"Was there no will?" asked Thorndyke.
"Under great pressure from the friends of his son's widow, the old man made a will shortly before he died; but he was then very old and rather childish, so the will was contested by Alfred, on the grounds of undue influence, and was ultimately set aside. Since then Alfred Hartridge has not paid a penny towards the support of his brother's family. If it had not been for my client, Mr. Curtis, they might have starved; the whole burden of the support of the widow and the education of the children has fallen upon him.
"Well, just lately the matter has assumed an acute form, for two reasons. The first is that Charles's eldest son, Edmund, has come of age. Mr. Curtis had him articled to a solicitor, and, as he is now fully qualified, and a most advantageous proposal for a partnership has been made, we have been putting pressure on Alfred to supply the necessary capital in accordance with his father's wishes. This he had refused to do, and it was with reference to this matter that we were calling on him this morning. The second reason involves a curious and disgraceful story. There is a certain Leonard Wolfe, who has been an intimate friend of the deceased. He is, I may say, a man of bad character, and their association has been of a kind creditable to neither. There is also a certain woman named Hester Greene, who had certain claims upon the deceased, which we need not go into at present. Now, Leonard Wolfe and the deceased, Alfred Hartridge, entered into an agreement, the terms of which were these: (1) Wolfe was to marry Hester Greene, and in consideration of this service (2) Alfred Hartridge was to assign to Wolfe the whole of his property, absolutely, the actual transfer to take place on the death of Hartridge."
"And
