An Apparent Resolution to the Affair of the Dog that did Not Bark.
You will recall, of course, the subtle and yet supremely logical manner in which Holmes resolved the mystery surrounding the death of the horse trainer, Stryker, and the disappearance of the racehorse Silver Blaze. That such precise and definite conclusions could be drawn from as fine a detail as that of a dog remaining silent has always been to me an exemplar of the heights of deductive reasoning to which the human intellect may rise.
We returned to London, having ascertained by painstaking investigation and keen observation that poor Stryker was felled, not by the hand of Simpson, the prime suspect in the eyes of the Constabulary, but rather by the iron-shod hoof of the horse, Silver Blaze.
Holmes chose not to disclose the whereabouts of that valuable beast to his owner. This seeming lapse has puzzled many followers of the inimitable sleuth, being on first examination a slight descent from the highly moral and ethical nature of his usual practice.
