Left in the Dark: No One on Board is a concealed-item puzzle-adventure game with creepy setting and a moody ambience. Private Detective Charlotte Austin knew after reading the letter from the Mayor of Portsmouth, this instance was going to be an odd one. In it, he asks her to solve the enigma of a ship that disappeared at sea and then reappeared a couple of weeks later with neither crew nor freight. Her initial attempts to draw logical conclusions predicated on the signs fail utterly. Charlotte realizes there may be something to the curse the local press is writing about. After encountering a hooded figure with a hook on a supposedly abandoned ship in a run of eerie events, she fears the puzzle is much darker and deeper than she initially thought. Charlotte has to detect what connects and a family’s unsolved homicide and the boat’s disappearance. But will she see the allies she must break the Curse of the Traveler?
