The ship of the Ghosts (#2). Philip D.

Molly and Arthur explored all the dark corridors and huge rooms of the Rivestorm mansion and thought that they already knew all the secrets of the estates... But one day they saw a ship with sails with sails torned into shreds. And then Molly found an old compass... This means that the Black Edward killer sharks is somewhere nearby! It turns out that many years ago, ghost pirates were seasoned on the island, and now they returned again to take revenge! And only Molly and Arthur can stop them! But... do they really hurry to the aid of stone Gorguls?!
