Robert Turold was not a man of intellect or action, but he belonged to a type which, as a rule, cling to life: the type from which zealots and bigots spring—men with a single idea. Such men shrink from the idea of destroying the vital engine by which their idea is driven forward. Their ego is too pronounced for that.
It was true that Robert Turold believed he had realized the aim for which he had lived, and therefore, in a sense, had nothing more to live for. But that point of view was too coldly logical for human nature. Its presumption was only applicable to a higher order of beings. No man had ever committed suicide upon achieving the summit of an ambition. There were always fresh vistas opening before the human mind.
Barrant left the study for the opposite room where the body of Robert Turold had been taken. It was his bedroom, and he had been laid upon the bed.
Death had not come to him easily. His harsh features were set in a stern upward frown, and the lower lip was slightly caught between the teeth, as though bitten in the final rending of the spirit. But Barrant had seen too much of violent death to be repelled by any death mask, however repellent.
He eyed the corpse closely, and then proceeded to examine the death wound. In doing so he had to move the body, and a portion of the sleeve fell back, exposing the left arm to the elbow. Barrant was about to replace it when his eye lighted upon a livid mark on the arm. He rolled back the garment until the arm lay bare to the shoulder. The disclosure revealed four faint livid marks running parallel across the arm, just above the elbow.
The arms had been straightened to the body to the elbows, and then crossed decorously on the breast. Barrant walked round to the other side of the bed, knelt down by the edge of it, and examined the underneath part of the arm. A single livid mark was imprinted upon it.
The inference was unmistakable. The four upper marks were fingerprints, and the lower one a thumb mark. Somebody had caught the dead man’s arm in such a strenuous grip that the livid impression had remained after death.
The discovery was significant enough, but Barrant was not at that moment prepared to say how much it portended. It seemed certain that the marks had not been made by Robert Turold himself. Their position suggested a left-hand clutch, though only a finger-print expert could definitely determine that point. Even if they were not, it was too far-fetched a supposition to imagine a man gripping his own arm hard enough to bruise it.
The relative weight of this discovery was, in Barrant’s mind, weakened by the fact that the marks might have been caused by the persons who had carried the body from the next room. Nevertheless, the marks must be regarded as infirmative testimony, however slight, of the fallibility of the circumstantial deductions which had been made from the discovery of the body in a locked room, with windows which could not be reached from the outside.
The presumption of suicide rested on the theory that the circumstances excluded any other hypothesis. But Barrant reflected that he did not know enough about the case to accept that assumption as warranted by the facts. The one certainty was that the study could not have been reached from the outside. Barrant had noted the back windows before entering the house; his subsequent interior examination had strengthened his conviction that they were inaccessible. Underneath the study windows there was only the narrowest ledge of rock between that side of the house and the edge of the cliffs. A descent from the windows with a rope was hazardously possible, but ascent and entrance by that means was out of the question.
