About this item

A continuation of USA TODAY bestselling author Leonard Goldberg's The Daughter of Sherlock Holmes, A Study in Treason is a new intriguing locked room mystery for Joanna and the Watsons to solve.

The following case has not previously been disclosed to the public due to the sensitive information on foreign affairs. All those involved were previously bound by the Official Secrets Act. With the passage of time and the onset of the Great War, these impediments have been removed and the story can now be safely told.

When an executed original of a secret treaty between England and France, known as the French Treaty, is stolen from the country estate of Lord Halifax, Scotland Yard asks Joanna, Dr. John Watson, Jr., and Dr. John Watson, Sr. to use their keen detective skills to participate in the hunt for the missing treaty. As the government becomes more restless to find the missing document and traditional investigative means fail to turn up the culprit, Joanna is forced to devise a clever plan to trap the thief and recover the missing treaty.

Told from the point of view of Dr. John Watson, Jr. in a style similar to the original Sherlock Holmes stories, A Study in Treason is based partly on facts in our world and partly on the facts left to us by Sir Arthur Conan Doyle.

Full of excitement and intrigue, this mystery is sure to be enjoyed by fans of Sherlock Holmes.



About the Author

Leonard Goldberg

Leonard Goldberg is an American physicist, professor of medicine, and the author of the Joanna Blalock series of medical thrillers. His novels have been translated into a dozen languages and sold more than a million copies worldwide. Leonard Goldberg is himself a consulting physician affiliated with the UCLA Medical Center, where he holds an appointment as Clinical Professor of Medicine. A sought-after expert witness in medical malpractice trials, he is board certified in internal medicine, hematology and rheumatology, and has published over a hundred scientific studies in peer-reviewed journals. Leonard Goldberg's writing career began with a clinical interest in blood disorders. While involved in a research project at UCLA, he encountered a most unusual blood type. The patient's red blood cells were O-Rh null, indicating they were totally deficient in A, B and Rh factors and could be administered to virtually anyone without fear of a transfusion reaction. In essence, the patient was the proverbial "universal" blood donor. This finding spurred the idea for a story in which an individual was born without a tissue type, making that person's organs transplantable into anyone without worry of rejection. His first novel, , revolved around a young woman who is discovered to be a universal organ donor and is hounded by a wealthy, powerful man in desperate need of a new kidney. The book quickly went through multiple printings and was optioned by a major Hollywood studio. Dr. Goldberg is a native of Charleston and a long-time California resident. He currently divides his time between Los Angeles and an island off the coast of South Carolina.
