Arthur Conan Doyle,
The case of Oscar Slater
(1912)
“ It may be argued that the existence of the hammer is such a point; but what household in the land is devoid of a hammer? It is to be remembered that if Slater committed the murder with this hammer, he must have taken it with him in order to commit the crime, since it could be no use to him in forcing an entrance. But what man in his senses, planning a deliberate murder, would take with him a weapon which was light, frail, and so long that it must project from any pocket? ”
