think so – without a doubt."
"But who was the invalid? Was he the real Sir Digby?"
"Aye, that's the question," said Edwards, thrusting his hands into his trouser pockets. For some moments we both sat staring blankly into the fire.
"Among the papers sent to us," he said very slowly at last, "was this. Read it, and tell me your opinion."
And then he took from his pocket-book and handed me a half-sheet of thin foreign notepaper, which had been closely written upon on both sides. It was apparently a sheet from a letter, for there was no beginning and no ending.
The handwriting was educated, though small and crabbed, and the ink brown and half-faded, perhaps because of its exposure to a tropical climate. It had been written by a man, without a doubt.
"That," said Edwards, "was found in a pocket-book belonging to Cane, which, in his hasty flight, he apparently forgot. According to our report the wallet was found concealed beneath the mattress of his bed, as though he feared lest anyone should read and learn what it contained. Read it, and tell me what you think."
I took the sheet of thin paper in my fingers, and, crossing the room to a brighter light, managed to decipher the writing as follows:
"… At fourteen paces from where this wall rises from the lawn stands the ever-plashing fountain. The basin is circular, while around runs a paved path, hemmed in by smoke-blackened laurels and cut off from the public way by iron railings. The water falls with pleasant cadence into a small basin set upon a base of moss-grown rockwork. Looking south one meets a vista of green grass, of never-ceasing London traffic, and one tall distant factory chimney away in the grey haze, while around the fountain are four stunted trees. On the right stretches a strip of garden, in spring green and gay with bulbs which bloom and die unnoticed by the hundreds upon hundreds of London's workers who pass and re-pass daily in their mad, reckless hurry to earn the wherewithal to live.
"Halt upon the gravel at that spot on the twenty-third of the month punctually at noon, and she will pass wearing the yellow flower. It is the only trysting-place. She has kept it religiously for one whole year without – alas! – effecting a meeting. Go there – tell her that I still live, shake her hand in greeting and assure her that I will come there as soon as ever I am given strength so to do.
"I have been at that spot once only, yet every detail of its appearance is impressed indelibly upon my memory. Alas! that I do not know its name. Search and you will assuredly find it – and you will see her. You will speak, and give her courage."
I bit my lip.
A sudden thought illuminated my mind.
The yellow flower!
Was not the mysterious woman whom I was to meet on the night of the fourteenth also to wear a yellow flower – the mimosa!
CHAPTER IV.
"DEAR OLD DIG."
I told Edwards nothing of Sir Digby's curious request, of his strange confidences, or of the mysterious letter to "E. P. K.", which now reposed in a locked drawer in my writing-table.
My friend, be he impostor or not, had always treated me strictly honourably and well. Therefore, I did not intend to betray him, although he might be a fugitive hunted by the police.
Yet was he a fugitive? Did not his words to me and his marvellous disguise prior to the tragedy imply an intention to disappear?
The enigma was indeed beyond solution.
At seven o'clock my visitor, finding necessity to revisit Harrington Gardens, I eagerly accompanied him.
There is a briskness and brightness in Piccadilly at seven o'clock on a clear, cold, winter's night unequalled in any thoroughfare in the world. On the pavements and in the motor-buses are thousands of London's workers hurrying to their homes in western suburbs, mostly the female employees of the hundreds of shops and work-rooms which supply the world's fashions – for, after all, London has now ousted Paris as the centre of the feminine mode – the shops are still gaily lit, the club windows have not yet drawn their blinds, and as motors and taxis flash past eastward, one catches glimpses of pretty women in gay evening gowns, accompanied by their male escorts on pleasure bent: the restaurant, the theatre, and the supper, until the unwelcome cry – that cry which resounds at half-past twelve from end to end of Greater London, "Time, please, ladies and gentlemen. Time!" – the pharisaical decree that further harmless merriment is forbidden. How the foreigner laughs at our childish obedience to the decree of the killjoys. And well he may, especially when we know full well that while the good people of the middle class are forced to return to the dulness of their particular suburb, the people of the class above them can sneak in by back doors of unsuspected places, and indulge in drinking, gambling, and dancing till daylight. Truly the middle-class Londoner is a meek, obedient person. One day, however, he may revolt.
Piccadilly was particularly bright and gay that night, as, passing the end of St. James's Street, we sped forward in the taxi towards Brompton Road and past the Natural History Museum to Gloucester Road.
On our arrival the door of the flat was opened by a constable without a helmet. Recognising the famous inspector, he saluted.
The body of the unknown girl had been removed to the mortuary for a post-mortem examination, but nothing else had been moved, and two officers of the C.I.D. were busy making examination for finger-prints.
I allowed them to take mine for comparison, but some they found upon the mahogany table and upon the back of a chair were undoubtedly those of the victim herself.
The small glass-topped specimen-table still lay where it had been overturned, and the fragments of the two green-glass flower-vases were strewn upon the carpet with the drooping red anemones themselves.
Regarding the overturned table the two detectives held that it had separated the assassin from his victim; that the girl had been chased around it several times before her assailant had thrown it down, suddenly sprung upon her, and delivered the fatal blow, full in her chest.
"We've thoroughly examined it for finger-prints, sir," the elder of the two officers explained to my companion. "Both on the glass top and on the mahogany edge there are a number of prints of the victim herself, as well as a number made by another hand."
"A man's?" I asked.
"No; curiously enough, it seems to be a woman's," was the reply.
"A woman's!"
I thought of that sweet perfume, and of the person who had lurked in the shadow of the stairs!
"That's interesting," remarked Edwards. "They may be those of the woman who wore green combs in her hair, or else of the porter's wife."
"The owner's man-servant is away abroad on business for his master, we've found out," answered the man addressed. "So of late the porter's wife, who lives in the basement of the next house, has been in the habit of coming in every day and tidying up the room. We took her prints this morning, and have found quite a lot about the place. No," added the man emphatically, "the finger-prints on that little table yonder are not those of the porter's wife, but of another woman who's been here recently. We only find them upon the door-handle and on the edge of the writing-table, against which the woman must have leaned. We'll have them photographed to-morrow."
The men then showed us the marks in question – distinct impressions of small finger-tips, which they had
