A good haunting yarn that takes place on the ‘Pole-Star,’ a whaling ship temporarily stuck in the northern ice floes. Capt. Nicholas Craigie’s vision of a ghostly wraith is seconded by the ship’s second mate and other superstitious sailors, and it is up to the ship’s doctor-narrator to hold it together until the ice breaks up and they can sail to safety. Perhaps it is not Doyle’s best tale, but interesting to see what he can do without Sherlock.
