Jay is swept into a mystery, beginning with who is hiding in the west wing of Keever house and why. Matters are complicated when Eliot, the cousin he hasn't seen for years and who has turned into a real nuisance, arrives on the island with his older brother Silas. Jay's has been told that Silas is a nasty piece of work and as far as he can see the description fits him perfectly. Will Silas and Eliot be responsible for causing trouble for Jay and his friends? Only time would tell.
