Be at the third pillar from the left outside the Lyceum Theatre tonight at seven o’clock. You are a wronged woman and shall have justice. Do not bring police. If you do, all will be in vain.

Soon they’re conducting dangerous moonlit expeditions to uncover the meaning of the sign of the four, and resolve a long-buried crime.
