Early one morning the curator of the Wallace Collection calls upon Sherlock Holmes requesting the Great Detective's assistance. Over the past few weeks, someone has been paying nocturnal visits to the gallery and apparently spending a great deal of time in one of the rooms devoted to medieval arms and armour. Although nothing appears to have been taken, the curator wants to know who is visiting after hours and why. When Holmes inspects the room, he makes a startling discovery that sets in motion a chain of events which ends up pitting Holmes against a modern day Templar.

Following his second marriage in 1907, Arthur Conan Doyle was looking to the future. The years ahead would see the birth of three children, fresh literary success and the discovery of his new faith. Those same years would also see the First World War, the final adventures of Sherlock Holmes, and ridicule from the religious and scientific communities for his beliefs.

The London of the late 19th century was home to both Arthur Conan Doyle and his famous detective Sherlock Holmes. This book looks at some of the many locations in both central and outer London that have connections to one or both of these famous names. In addition to examining the history this book also looks at some of the theories that have been woven over the years around Holmes and these locations.

With contributions from Stephen Fry, Mark Gatiss, Douglas Wilmer, and many more, this book was put together by fan site Sherlockology to help save Undershaw, the former home of Sir Arthur Conan Doyle.

Undershaw was the Surrey home of Arthur Conan Doyle between 1897-1907. Built lovingly for his wife Touie to help treat her ongoing battle with tuberculosis, Arthur created a haven for his wife and family. It was here he wrote The Hound of The Baskervilles, brought Sherlock Holmes back to life in "The Empty House", and entertained guests such as writer J.M. Barrie, illustrator Sidney Paget, renowned actor William Gillette, and more.
