To me the theory was worthless, for the horse thieves would not have unhaltered four horses and turned them loose in a barn, but would have haltered them and led them quietly out. It was a case where, the general history of all concerned, prior to the crime, supplied the possibility of an adequate motive in the form of a desire to be rid of Findlay. The woman's grief was sham. McLean's thirst in the summer which caused him to walk unannounced into the kitchen of the Findlay house, led to the clue that caused me, upon seeing how unreal was the woman's sorrow, to crowd her for a confession. Her imagination pictured to her the crime when she strove in vain to shut it out.
Imagination is the key that has unlocked the secret of many a crime.
Imagination conjures up all the potent fears that the guilty dread. It causes many crimes but it also betrays many a criminal.
