It was the same next day, when, for some five hours out of a possible five and a half, the attention of the court was concentrated upon a point of obviously secondary significance. It was suggested by the defence that the watch and chain found up the study chimney were not those worn by the deceased at the time he met his death. The contention was supported by photographs of Alexander Minchin wearing a watch-chain that might or might not be of another pattern altogether; expert opinions were divided on the point; and experts in chains as well as in photography were eventually called by both sides. Interesting in the beginning, the point was raised and raised again, and on subsequent days, until all were weary of the sight of the huge photographic enlargements, which were handed about the court upon each occasion. Even the prisoner would droop in her chair when the "chain photograph" was demanded for the twentieth time by her own unflagging counsel; even the judge became all but inattentive on the point, before it was finally dropped on an intimation from the jury that they had made up their minds about the chains; but no trace of boredom had crossed the keen, alert face of the unknown gentleman with the snowy hair. So the case was fought for Mrs. Minchin, tooth and nail indeed, yet perhaps with more asperity than conviction, and certainly at times upon points which were hardly worth the fighting. Yet, on the Friday afternoon, when her counsel at last played his masterstroke, and, taking advantage of the then new Act, put the prisoner herself in the witness-box, it was done with the air of a man who is throwing up his case. The truth could be seen at a glance at the clean-cut, handsome, but too expressive profile of the crushing cross-examiner of female witnesses and insolent foe to the police. As it had been possible to predict, from the mere look with which he had risen to his feet, the kind of cross-examination in store for each witness called by the prosecution, so it was obvious now that his own witness had come forward from her own wilful perversity and in direct defiance of his advice.
