Miss Mary Morstan has received a single, valuable pearl every year on the same day for the last six years. The sender has remained anonymous - until now. This year, a note was included with the pearl: Be at the third pillar from the left outside the Lyceum Theater at ten o'clock. If you are distrustful, bring two friends. You are a wronged woman, and you will have justice. Do not bring police. If you do, all will be lost. - Your unknown friend.
Unsure of who to turn to, Miss Morstan makes her way to 221b Baker Street and asks Holmes and Watson for their help. Holmes is fascinated by the case, Watson is fascinated by the beautiful Miss Mary Morstan - of course both men agree to offer their assistance. But how could any of them know that the six pearls would lead them to a stolen treasure, a secret and deadly pact between four criminals, and two corrupt prison guards?
