Sherlock Holmes. The Sign of the Four

Be at the "Lyceum" theater today at seven o'clock, third column on the left. If you have doubts, bring two friends with you. You are the aggrieved party, and this needs to be corrected. Do not bring the police. If you do, it will all be in vain. When Holmes is asked to examine a mysterious message received by Mary Morstan, neither he nor Watson suspects that they will be drawn into a web of betrayal woven decades ago. Now they must conduct a dangerous investigation to understand the meaning of the sign of the four and uncover a long-forgotten crime.
