Publisher's Synopsis
Hilda Wade Hilda is a detective and a nurse, admired by Dr. Hubert Cumberledge, and it is with his support and her logical thinking that drives her to a secret purpose. This is Grant AIlen's last work before his death and the last chapter was sketched before hish death. His friend and neighbour, Sir Arthur Conan Doyle, gathered his ideas, and wrote it out for him in the form in which it now appears.
