海伦瓦登的招供(Helen Vardon's Confession)简介：

R. Austin Freeman was a British writer of detective stories, mostly featuring the medico-legal forensic investigator Dr. Thorndyke. He invented the inverted detective story (a crime fiction in which the commission of the crime is described at the beginning, usually including the identity of the perpetrator, with the story then describing the detective's attempt to solve the mystery) and used some of his early experiences as a colonial surgeon in his novels. A large proportion of the Dr. Thorndyke stories involve genuine, but often quite arcane, points of scientific knowledge, from areas such as tropical medicine, metallurgy, and toxicology.
