Hugo II: Whodunit?

Hugo and his wife, Penelope, arrive to stay at the mansion that belongs to Hugo's Great Uncle Horace. Penelope falls asleep in the bedroom, while Hugo accidentally finds a bookcase passage and is locked in a secret room. Penelope wakes up, only to witness Uncle Horace's murder through the keyhole. The player controls Penelope (and later, briefly, Hugo) and must solve the murder.
