The Problem of Thor Bridge

A Sherlock Holmes Story

Sir Arthur Conan Doyle


The story is remarkable for the initial reference to a tin dispatchbox, hidden in a bank, where Dr Watson kept the papers concerning various Holmes' cases.


In this story, Maria Gibson was found lying in a pool of blood on Thor Bridge with a bullet through the head and note from the governess, agreeing to a meeting at that location, in her hand.
