determined to drag him boldly into the open.
‘Are you a detective?’ inquired the girl. ‘How exciting! Dad only told us you were a friend of his.’
Heldway went imperturbably on with his sweet. ‘Yes, I am a detective, Miss Fleeting. I’m afraid it is not so exciting as the novelists would have you believe. How did you know?’ He addressed Vernet.
The other shrugged his shoulders. ‘I didn’t recall your face till this moment,’ he answered indifferently. ‘I saw you give evidence at the Old Bailey in a murder case last year. Are you down here on business?’
It was difficult for Heldway to repress a laugh. Whether Vernet was a rogue or not, he was not so simple as not to put a construction on the circumstances. ‘An official of police is always more or less on business,’ he parried. ‘But I’m here, through Mr Fleeting’s kindness, only for fresh air.’
‘So you haven’t brought your handcuffs?’ Vernet was smiling inwardly. The official wondered if he meant a challenge.
‘I don’t anticipate any occasion to use them down here,’ he laughed.
Fleeting, who had been fidgeting uneasily in his chair, broke in: ‘Here’s coffee. Have a cigar, Heldway. My daughter doesn’t mind. I never ask Vernet. He’s got his own particular brand of poisonous cigarettes. I believe he smokes them in his sleep.’
‘It’s a bad habit,’ said Vernet. ‘If I had any strength of will I should give them up. But I’m lost without a cigarette.’ He extracted a fat one from a gold case, and lighting it, blew a circle of smoke into the air. ‘If I were a criminal, now, there would be a clue for you, Mr Heldway. You’d only have to look for an insatiable consumer of cigarettes, like Raffles, eh?’
He held the white tube up to the light. ‘I have them specially made, with my initials on the paper.’
‘The perfect criminal—and thank Heaven there is none—would have no fixed habits,’ commented Heldway.
It was late in the evening before he got the chance of a word alone with his host. Miss Fleeting had accepted the diamond-maker’s challenge to billiards, and the two elder men were contemplating the moonlight from the veranda. Fleeting was anxious to make it clear that he had given no hint of the detective’s identity. Heldway brushed away his explanation.
‘Never mind about that. You haven’t shown me over the house yet. Suppose we take the opportunity now.’
‘I didn’t suppose you’d be interested. It’s entirely modern. However, come along.’
So it was that, when he retired, the detective had in his mind a very complete plan of the sleeping apartments of the house, especially the relation of his own bedroom to that occupied by Vernet. Beyond taking off his boots and collar, he had made no attempt to undress, He stretched himself out in an arm-chair with a novel, and composed himself to read until such a time as the household should be asleep. At two o’clock he laid aside his book and rummaged in his kit bag. A small electric torch about the size of an ordinary match-box, a dozen master-keys, and a red silk handkerchief with a couple of holes cut in it rewarded his search. The handkerchief he adjusted on his face, the holes serving as eye-slits. The keys and the torch he carried in his hands.
There are moments when a police officer steps out of the limits of strict legality. He knows how great a risk he runs, for if he fails of his purpose he can expect no countenance from his superiors. There was no possible excuse for Heldway in what was, in effect, an act of burglary. He had deliberately refrained from saying anything to Fleeting of his intention, partly, it must be admitted, because he was afraid that the jeweller might exercise a veto.
Softly he stepped into the corridor, his stockinged feet making no sound on the soft carpet. A thin thread of light cut through the darkness, affording just enough light to prevent his blundering into any furniture. More than once he switched off the light and stood stock still as his ear caught those indefinite sounds that are always audible in a sleeping household.
He reached Vernet’s door and softly turned the handle. As he expected, it was locked.
Very stealthily he tried his keys one after the other.
His muscles contracted involuntarily as a slight click told that the bolt had shot back. He stood stiffly, listening intently.
Five minutes elapsed before he ventured to thrust open the door and cautiously edge his way inside. He waited for a matter of seconds till the deep regular breathing from the bed reassured him. Then he flashed the bead of light on the wardrobe, and all his movements quickened. Whatever he sought he had guessed the diamond-maker would carry on him during the day—otherwise Heldway would not have waited till now to ransack the room.
Presently he gave an almost unconscious ejaculation of triumph, as he dragged out of a pocket a little wash-leather bag. With hasty fingers he opened it and directed the rays of his lamp on twenty or thirty uncut diamonds. And then, even while he chuckled to himself, the room was suddenly flooded with light. He wheeled abruptly. Vernet was sitting up in bed, one hand on the electric light switch, the other holding a revolver, its muzzle steadily directed towards Heldway.
‘Stand still, my friend.’ Vernet’s voice was cold and menacing. ‘Perhaps it would be as well if you put your hands above your head.’ His own hand had deserted the switch and began groping for the bell. ‘I see you have masked your face—a wise precaution.’
Heldway lowered his head, swerved sideways, and plunged forward so swiftly that it seemed as if all his movements were simultaneous. A quick report rang out, and a bullet shattered the glass of the wardrobe. Before Vernet’s finger could compress on the trigger again, Heldway was upon him. His full weight was behind his left as he swung it to Vernet’s jaw, and the man dropped limply back on his pillow.
The detective fled. It was a matter of seconds from the time Vernet had fired till he reached his own room and closed and locked the door. He could hear people rushing about and sleepy voices raised in inquiry. Hastily he tore off his clothes and tumbled into his pyjamas. A thunderous knock interrupted him before he had finished. He continued an audible yawn the while he ruffled his bed noiselessly to give it the appearance of having been slept in, and in his voice as he put a question was the querulous tone of a man just aroused.
‘It’s me—Fleeting. Wake up. There’s been burglars. They’ve murdered Vernet.’
‘Good heavens!’ There was a fervour that was unfeigned in the detective’s voice. He had had no time to calculate his blow with nicety, and trusted that he had not struck harder than he meant. A moment later he flung open the door, and while Fleeting waited, put on his slippers and dressing-gown. His alibi was convincing.
They went together to the diamond-maker’s room. He was relieved to find that Vernet was very far from dead, though still unconscious. ‘Somebody has knocked him out, that’s all,’ he diagnosed. ‘He’ll be all right in a little while.’ He turned on the group of servants who had gathered in the room. ‘Some of you men get out into the grounds. The burglar can’t have got far.’
‘Hadn’t someone better go for the police?’ said the jeweller.
‘Not worth while. They can do nothing tonight that we can’t do without them. If we don’t catch the man ourselves, I’ll run out to put the case in their hands myself.’
No one disputed his authority. He calculated that the flustered men-servants would make enough confusion in the garden to keep up the illusion of a burglar, and he did not want to have to cause the local police useless trouble. Nevertheless, after seeing Vernet comfortably disposed, he went to direct the search. He it was, curiously enough, who discovered a broken pane of glass in an unfastened scullery window—proof of the means by which the burglar had effected an entrance.
Nothing resulted from a search of the grounds. One man at least had scarcely expected there would. He was undecided whether to take Fleeting into his confidence. If all had gone well he would have done so—indeed, it would have been necessary to his plan.
‘I
