If you had the power to summon the ghost of someone and they appeared in person and you could talk to that ghost and that ghost could talk back, like answer any questions you have, who are the top 3 people on your list whose ghost you would most like to see and talk with. For me it would be: 1. Charlie Lawson 2. Jack the Ripper 3. Any one of the people who died on the ship Titanic when it went down.
