Sir William Brett waited for over half an hour at the house of the patient for the benefit of whose health, and relief of whose pocket, the consultation had been arranged. Then he rang up Dr. Merson’s house for an explanation. He received a reply (after some delay) that the doctor had been seized with a sudden indisposition, and greatly regretted that the appointment must be deferred until the following day.

The inquest on the body of Peter Corner had been twice adjourned by a coroner who had known Dr. Merson sufficiently well to regard it as incredible that he should have committed a crime so strange and so inexplicable. He hoped that the doctor might be found, and that his voluntary return would furnish some satisfactory explanation. But the police had not been retarded by any similar hesitation. Within twenty-four hours of the doctor’s disappearance the dismembered body of Peter Corner had been discovered, and the facts that the doctor could not be found, and that he had drawn nearly four hundred pounds (practically the whole of his available balance) from his bank in Treasury notes on the previous day, had enabled them to obtain a warrant for his arrest without difficulty.
But the warrant had not been executed.
Dr. Merson had walked to the station quite openly. He had chatted with casual acquaintances on the platform. He had even got into a compartment containing others who knew him. He had traveled to London, saying that he was in search of certain surgical instruments which he required to renew, and had disappeared absolutely.
It was agreed that he had been in particularly good spirits. Indeed — and this was one of the minor mysteries of the case — there had been a noticeable change in his demeanor from the morning when Peter had been seen to enter the door of his surgery. Every one had noticed the change. It was as though a load of fear or trouble had been suddenly lifted from him.
Mrs. Merson — who had insisted on giving evidence, in spite of the coroner’s warning — had confirmed this. She had entered the witness box to urge her conviction, against the weight of overwhelming evidence, that he had not murdered Peter at all, and to assert that he had himself been living in dread of some mysterious enemy, who must be responsible both for the fate of Peter, and for her husband’s disappearance.
Her evidence, given with the convincing simplicity of an unimaginative mind, had impressed its hearers with her sincerity, and increased the sympathy with which she was regarded, but it could not shake the weight of evidence which placed the crime upon the shoulders of the absent doctor.
It was admitted by the police that the doctor could not have known that Peter would be released from school on the fatal morning, but their theory was that he had met the boy by chance in the street, and had recognized an unexpected opportunity for the commission of a crime which had been designed within his mind previously. He had told the boy to go to the surgery, and await his return. He had followed immediately, by a different route, entering the surgery unobserved, and promptly disposed of his unsuspecting victim. His household admitted that they had not known that he was at home till the telephone inquiry from Sir William Brett had caused them to seek him, and he had then replied through a half-opened door, that he was unwell, and the appointment must be deferred to the following day.
He had callously proceeded to the dissection of his victim’s body, and it was only when the police had traced the missing boy to his own door, and the inquiries had become too close and pointed for his comfort, that he had decided that it would be best to bolt, without delaying for the added risk of attempting the destruction or removal of the dismembered corpse.
Such was the theory of the police, and while it failed to offer the explanation of any adequate motive for a deed so ghastly, and a risk so great, and while there was nothing in the doctor’s previous record to support the suggestion of criminality at once so gross and so reckless, yet it had the advantage of meeting the admitted facts more plausibly than appeared otherwise possible, and even those who were least willing to believe that the doctor could have been guilty of such a murder were unable to put forward any reasonable supposition which could explain the presence of the boy’s remains on his premises, and his subsequent flight and silence.
