The Cask by Freeman Wills Crofts — Read

La Touche, having finished his report, put on his hat and sallied forth into the rue de la Fayette. He intended after posting his letter to cross to the south side and spend the evening with some friends. He was not in an agreeable frame of mind. The conclusion to which he was apparently being forced would be a disappointment to Clifford, and, if the theory of Boirac's guilt broke down, he saw no better than the solicitor what defence remained.

He sauntered slowly along the pavement, his mind brooding almost subconsciously on the case. Then, noticing a letter-box on the opposite side of the street, he turned to cross over. But as he stepped off the sidewalk an idea flashed into his mind and he stopped as if shot. That typewriter the pretty girl in Boirac's office had been using was a new machine. La Touche was an observant man, and he had noted the fact, as he habitually noted small details about the objects he saw. But not until this moment did he realise the tremendously suggestive deduction which might be made from the fact. Lefarge, in his search for the machine on which the Le Gautier letter had been typed, had obtained samples from all the typewriters to which Boirac, so far as he could ascertain, had access. But what if that new machine replaced an old? What if that old machine had typed the Le Gautier letter and had been then got rid of so that samples taken by suspicious detective might be supplied from some other typewriter? Here was food for thought. If he could prove anything of this kind he need have no fear of disappointing his employer. He put the report back in his pocket till he could adjust himself to this new point of view.
