This movie was meant for TV and it originally aired in the 60’s but I saw it in the 70’s. All these famous detectives were told to come to some mansion to solve a mystery. I think their names were Charlie Chan, Agatha Christy, and others. All the rooms in the mansions rooms seem to change around constantly. In the end, Sherlock Holmes is coming to figure the mystery out. I kind of remember Sherlock getting lost and asking someone for directions. That’s all I have, please help me!
