The Sign of Four
by Arthur Conan Doyle
This is the second book in the Sherlock Holmes Series.
A Miss Mary Morstan brings in an interesting case. Her father, an officer in the British Army, has disappeared ten years earlier. For the last six years, every year, someone has been sending her a small box, containing nothing but a large pearl. Now, a cryptic letter. A series of bizarre murders ensue.
Join Holmes and Watson as they solve this puzzling case. In this book, Holmes utters the now-famous maxim: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth."
