Six hundred years ago the small town of Tallacombe, in Devonshire, England, was granted a Charter of the Liberty of the Royal Port of Falmouth. As a resident of the town you are attending a dinner at the start of the 600th anniversary celebrations: the dinner is taking place in a local hotel situated picturesquely on the coast above a rugged sea cliff.

But more recent local memories are also stirring. There may be dangerous currents below the surface of this peaceful occasion.

Should there be unexpected sinister developments, the police may want your help in solving a problem. Keep your eyes and ears open and be prepared to use your wits.
