When is detective a good criminologist? When he has a good partner. When is a 'Who Dun It' a good mystery? When it is full of twist and turns, murders, scams, secrets, revenge and villains. When is a crime solved? When the clues reveal a motive. What trips up a villain in getting caught? When they believe they have all the answers, and fall prey to their own stupidity in believing no one is on to them. Can even a villain trust his own comrades, even if they are his faithful son's? Do the walls have ears, and eyes? Do you believe in Ghost? Are Ghost real or a figment of your imagination? I dare you to believe in Ghost. Our criminologist does. And they make a great team in solving the Morris Hotel mystery.
