the letter. But clear and perfect and without possibility of doubt was the print of a forefinger to the right of the flap, and the forefinger was the same forefinger that had left its mark on the revolver found in the dead man’s pocket.
“Well, that fits your theory about the friend who supplied the gun, doesn’t it?” said Grant.
But the sergeant made a queer choked noise and continued to look at the print.
“What’s the matter? It’s as clear as a kid’s alphabet.”
The sergeant straightened himself and looked queerly at his superior. “I’ll swear I hadn’t a glass too much, sir. But it’s either that or the whole fingerprint system is balmy. Look at that!” He pointed with a not too steady forefinger at a print in the extreme lower right-hand corner, and as he did so he shoved the dead man’s fingerprints, which had lain slightly apart, under Grant’s nose. For a little there was silence while the inspector compared the prints and the sergeant, over his shoulder, half-fearfully corroborated his previous view. But there was no getting away from the fact that faced them in irrefutable whorls and ridges. The fingerprint was that of the dead man.
It was only a moment or two before Grant realized the simple significance of that apparently staggering fact.
“Communal notepaper, of course,” he said offhandedly, while his looker-on half mocked at him for having allowed himself to be victimized even for a moment by the childish amazement that had overcome him. “Your theory blossoms, Williams. The man who lent the gun and provided the money lived with the dead man. That being so, of course he can spin any kind of yarn he likes to his landlady or his wife or whoever would be interested about the disappearance of his chum.” He took up the telephone on his desk. “We’ll see what the handwriting people have to say about the piece of notepaper.”
But the handwriting experts had nothing to add to what Grant already knew or guessed. The paper was of a common type that could be bought at any stationer’s or bookstall. The printing was that of a man. Given a specimen of a suspect’s handwriting, they would probably be able to say whether or not the printing had been done by him, but so far they could be of no more help than already indicated.
Williams departed to his temporarily bereaved home to comfort his uxorious mind by reminding himself how short a week was, and how pretty Mrs. Williams would be when she came back from Southend; and Grant remained where he was, trying to mesmerize the dagger into giving up its tale. It lay on the dark green leather surface of his desk, a graceful, wicked toylike thing, its business end in its slender viciousness making a queer contrast to the bluff saint on the handle with his silly, expressionless face. Grant considered the saintly features sardonically. What was it Ray Marcable had said? You’d want a blessing on an undertaking as big as that. Well, Grant thought, he would choose a more potent saint as O.C. affairs than the ineffectual holy one on the handle. His thoughts went to Ray Marcable. This morning’s press had been full of her projected departure for America, the popular papers expressing themselves in lamentation and the more high-brow in bitterness and indignation that British managers should allow the best musical comedy star of a generation to leave the country. Should he go to her, Grant wondered, before she left and ask her bluntly why she had looked surprised at the description of the dagger? There had been nothing to connect her even remotely with the crime. He knew her history—the little semi-detached villa in a dreary suburb that she had called home, the council school she had attended, her real name, which was Rosie Markham. He had even met Mr. and Mrs. Markham over the affair of the suitcase. It was exceedingly unlikely that she could throw any light on the Queue Murder. And it was still more unlikely that she would if she could. She had had her chance to be frank with him over that tea in her dressing-room, and she had quite deliberately kept him outside any knowledge she might have had. That knowledge, of course, might be entirely innocent. Her surprise might have been due to recognition of the dagger’s description, and yet have nothing to do with the murder. The dagger was far from unique, and many people must have seen and handled similar weapons. No, either way he was not likely to get much satisfaction from another interview with Miss Marcable. She would have to depart for the United States uninterrogated.
With a sigh for its unproductiveness he locked the dagger away in its drawer again and set off for home. He came out on to the Embankment to find that it was a fine night with a light, frosty mist in the air, and he decided that he would walk home. The midnight streets of London—always so much more beautiful than the choppy crowded ones of the daytime—fascinated him. At noon London made you a present of an entertainment, rich and varied and amusing. But at midnight she made you a present of herself; at midnight you could hear her breathe.
When at length he turned into the road where he lived he had come to the stage of walking automatically, and a starry mist possessed his brain. For a little while Grant had “shut his eyes.” But he was not asleep, actually or metaphorically, and the eyes of his brain opened with a start at the dim figure that was waiting on the opposite corner just outside the lamplight. Who was hanging about at this hour?
He debated rapidly whether or not to cross and walk down the other side of the street, and so come within criticizing distance of the figure. But it was rather late to change his direction. He held on, ignoring the loiterer. Only when he was turning in at his own gate he looked back. The figure was still there, almost indistinguishable in the gloom.
It was after twelve when he let himself in with his latchkey, but Mrs. Field was waiting up for him. “I thought you’d like to know that there has been a gentleman here asking for you. He wouldn’t wait and he wouldn’t leave a message.”
“How long ago was that?”
More than an hour, Mrs. Field said. She didn’t see him rightly. He had stood well out beyond the step. But he was young.
“No name?”
No, he had refused to give a name.
“All right,” said Grant. “You go to bed. If he comes back, I’ll let him in.”
She hesitated in the doorway. “You won’t do anything rash, will you?” she said solicitously. “I don’t like the thought of you bin here all alone with some one who might be an anarchist for all we know.”
“Don’t you worry, Mrs. Field. You won’t be blown up tonight.”
“It isn’t blowing up I’m afraid of,” she said. “It’s the thought of you lyin’ here perhaps bleeding to death and no one knowing. Think how I’d feel when I came in in the morning and found you like that.”
Grant laughed. “Well, you can comfort yourself. There isn’t the slightest chance of anything so thrilling happening. No one has ever spilt my blood except a Jerry at Contalmaison, and that was more by luck than good management.”
She conceded the point. “See and have a bite before you go to bed,” she said, indicating the food on the sideboard. “I got you some English tomatoes, and the beef is Tomkins’ best pickled.” She said good night and went, but she could not have reached her kitchen before a knock sounded on the door. Grant heard her go to the door, and even while his brain was speculating about his visitor, the looker-on in him was wondering whether it was spunk or curiosity that had sent Mrs. Field so willingly to answer the knock. A moment later she threw open the sitting-room door and said, “A young gentleman to see you, sir,” and into Grant’s eager presence came a youth of nineteen or twenty, fairly tall, dark, broad-shouldered, but slight, and poised on his feet like a boxer. As he came forward he shot a furtive glance from his brilliant dark eyes into the corner behind the door, and he came to a halt some yards from the inspector in the middle of the room, turning a soft felt hat in his slim gloved hands.
“You are Inspector
