He takes us:
Aboard Erebus and Terror on Sir John Franklin's disastrous Arctic expedition, last seen parting from their escort...
Aboard the Mary Celeste, crewed by a well-respected captain and an experienced crew, abandoned in the mid-Atlantic...
Aboard the battleship Maine, blown sky-high in Havana harbour...
Aboard the collier Cyclops, disappeared between Barbados and Virginia during the First World War...
Aboard the Teignmouth Electron, winner-apparent of the round the world yacht race, sighted deserted and drifting...
This is life at sea at its most epic and frightening.
