The Last Test is a classic American horror story by H. P. Lovecraft. Few persons know the inside of the Clarendon story, or even that there is an inside not reached by the newspapers. It was a San Francisco sensation in the days before the fire, both because of the panic and menace that kept it company, and because of its close linkage with the governor of the state. Governor Dalton, it will be recalled, was Clarendon's best friend, and later married his sister. Neither Dalton nor Mrs. Dalton would ever discuss the painful affair, but somehow the facts have leaked out to a limited circle.
