A New York Times Bestselling Author
In 1910, Dr. John Watson travels to Egypt with his wife. Her tuberculosis has returned and her doctor recommends a stay at a sanitarium in a dry climate. But while his wife undergoes treatment, Dr. Watson bumps into an old friend, Sherlock Holmes, in disguise and on a case. An English duke has disappeared, leading to enquiries from his wife and the Home Office. Holmes has discovered that the missing duke was on the trail of a previously undiscovered and unopened tomb. Holmes and Watson are on the trail of something much bigger, more important, and more sinister than an errant lord.
