recurred to him which had been in his mind since he had heard the superintendent’s first statement. Suppose Orchard was the man. Suppose Orchard, visiting the office in the evening, arrived to find the safe open and the old man stooping over it. Instantly he would be assailed by a terrible temptation. The thing would seem so easy, the way of escape so obvious, the reward so sure. French, sitting back in the arm-chair, tried to picture the scene. The old man bending over the safe, the young one entering, unheard. His halt in surprise; the sudden overwhelming impulse to possess the gems; his stealthy advance; the seizing of the poker; the blow, delivered perhaps with the intention of merely stunning his victim. But he strikes too hard, and, horrified by what he has done, yet sees that for his own safety he must go through with the whole business. He recalls the danger of finger prints, and wipes the handles of the poker and of the drawer in the safe from which he has abstracted the diamonds. With admirable foresight he waits until the body grows cold, lest an examination of it by the policeman he intends to call might disprove his story. Then he rushes out in an agitated manner and gives the alarm.
Though this theory met a number of the facts, French was not overpleased with it. It did not explain what Gething was doing at the safe, nor did it seem to fit in with the personality of Orchard. All the same, though his instruction to his man to shadow Orchard had been given as an obvious precaution inevitable in the circumstances, he was glad that he had not overlooked it.
Another point occurred to him as he sat thinking over the affair in the leather-lined chair. If Orchard had stolen the stones, he would never have risked having them on his person when he gave the alarm. He would certainly have hidden them, and French could not see how he could have taken them out of the building to do so. A thorough search of the offices seemed therefore called for.
The inspector was tired, but, late as it was, he spent three solid hours conducting a meticulous examination of the whole premises, only ceasing when he had satisfied himself beyond possibility of doubt that no diamonds were concealed thereon. Then, believing that he had exhausted the possibilities of the scene of the crime, he felt himself free to withdraw. Dawn was appearing in the eastern sky as he drew the door after him and set off in the direction of his home.
The fact that he had been out all the previous night was not, in Inspector French’s eyes, any reason why he should be late at his work next day. At his usual time, therefore, he reached New Scotland Yard, and promptly engaged himself in the compilation of a preliminary report on the Hatton Garden crime. This completed, he resumed direct work on the case.
There were still several obvious inquiries to be made, inquiries which might almost be called routine, in that they followed necessarily from the nature of the crime. The first of these was an interview with the other members of the Duke & Peabody staff.
An Oxford Street bus brought him to the end of Hatton Garden, and soon he was once more mounting the staircase to the scene of his last night’s investigation. He found Mr Duke standing in the outer office with Orchard and the typist and office boy.
‘I was just telling these young people they might go home,’ the principal explained. ‘I am closing the office until after the funeral.’
‘That will be appreciated by poor Mr Gething’s family, sir. I think it is very kind of you and very proper too. But before this young lady and gentleman go I should like to ask them a question or two.’
‘Of course. Will you take them into my office? Go in, Miss Prescott, and tell Inspector French anything he wants to know.’
‘I’m afraid you won’t be able to do quite so much as that, Miss Prescott,’ French smiled, continuing to chat pleasantly in the hope of allaying the nervousness the girl evidently felt.
But he learned nothing from her except that Mr Duke was a very nice gentleman of whom she was somewhat in awe, and that Mr Gething had always been very kind to her and could be depended on to let her do whatever she wanted. Neither about the clerk, Orchard, nor the pupil, Harrington, was she communicative, and the office boy, Billy Newton, she dismissed as one might a noxious insect, a negligible, if necessary, evil. Mr Gething had been, as far as she could form a conclusion, in his usual health and spirits on the previous day, but she thought he had seemed worried and anxious for the past two or three weeks. As to herself, she liked the office, and got on well with her work, and was very sorry about poor Mr Gething. On the previous day she had gone straight from the office, and had remained at home with her mother during the entire evening. French, satisfied she had told him all that she knew, took her finger prints and let her go.
From Billy Newton, the precocious office boy, he learned but one new fact. Newton, it seemed, had been the last to leave the office on the previous evening, and before Mr Gething had gone he had instructed him to make up the fire in the chief’s office, as he, Gething, was coming back later to do some special work. The boy had built up a good fire and had then left.
When French returned to the outer office, he found a new arrival. A tall, good-looking young man was talking to Mr Duke, and the latter introduced him as Mr Stanley Harrington, the clerk-pupil who was qualifying for a partnership. Harrington was apologising for being late, saying that on his way to the office he had met an old schoolfellow of whom he had completely lost sight, and who had asked him to accompany him to King’s Cross, whence he was taking the 9.50 a.m. train for the north. The young man seemed somewhat ill at ease, and as French brought him into the inner office and began to talk to him, his nervousness became unmistakable. French was intrigued by it. From his appearance, he imagined the man would have, under ordinary circumstances, a frank, open face and a pleasant, outspoken manner. But now his look was strained and his bearing furtive. French, with his vast experience of statement makers, could not but suspect something more than the perturbation natural under the circumstances, and as his examination progressed he began to believe he was dealing with a normally straightforward man who was now attempting to evade the truth. But none of his suspicions showed in his manner, and he was courtesy itself as he asked his questions.
It seemed that Harrington was the nephew of that Mr Vanderkemp who acted as traveller for the firm. Miss Vanderkemp, the Dutchman’s sister, had married Stewart Harrington, a prosperous Yorkshire stockbroker. Stanley had been well educated, and had been a year at college when a terrible blow fell on him. His father and mother, travelling on the Continent, had both been killed in a railway accident near Milan. It was then found that his father, though making plenty of money, had been living up to his income, and had made no provision for those who were to come after him. Debts absorbed nearly all the available money, and Stanley was left practically penniless. It was then that his uncle, Jan Vanderkemp, proved his affection. Out of his none too large means he paid for the boy’s remaining years at Cambridge, then using his influence with Mr Duke to give him a start in the office.
But shortly after he had entered on his new duties an unexpected complication, at least for Mr Duke, had arisen. The principal’s daughter, Sylvia, visiting her father in the office, had made the acquaintance of the well-mannered youth, and before Mr Duke realised what was happening the two young people had fallen violently in love, with the result that Miss Duke presently announced to her horrified father that they were engaged. In vain the poor man protested. Miss Duke was a young lady who usually had her own way, and at last her father was compelled to make a virtue of necessity. He met the situation by giving the affair his blessing, and promising to take Harrington into partnership if and when he proved himself competent. In this Harrington had succeeded, and the wedding was fixed for the following month, the partnership commencing on the same date.
French questioned the young fellow as to his movements on the previous evening. It appeared that shortly after reaching his rooms on the conclusion of his day’s work in the office, he had received a telephone message from Miss Duke saying that her father had just called up to say he was detained in town for dinner, and, being alone, she wished he would go out to Hampstead and dine with her. Such an invitation from
