When Eleanor and William first board the Little Noah, they do not expect to run into each other after years of not having met. Time seems to stand still when they encounter each other, but all is not as well as it seems. They have a history of love, violence, and betrayal. The other passengers include the rich businessman, Mr Farhan Khanna, and the innocent journalist, Mia. Also traveling on the ship are Martin, Oliver and Mary.
Eleanor had been hoping for a quiet vacation but only a couple of days after the ship starts sailing, events take a sinister turn when one of the passengers is found murdered. And not only does the passenger seem to have been murdered quite skilfully, but the stabs on his body are also mysteriously shaped like a triangle. All the passengers appear to have a motive and everyone is a suspect! Eleanor is asked to take on the case and find the murderer's identity, but she must race against time and find the murderer before the ship reaches the shore. Martha's haunting presence further complicates matters. Who is Martha? Does she have anything to do with the events that take place aboard the ship? Will Eleanor be able to solve the mystery? Will she succeed in her mission?
