A young explosives expert called Semenkin is found murdered in his Jamaican hotel room whilst posing as a French businessman. In his pocket is a newspaper advertisement reading 'Wanted: A Parrot that Speaks Greek. Reply Box 666' though the sixes have been altered to eights. Realizing it is a secret code, Tremayne sends Craig to the Caribbean to assume the dead man's identity. He falls in with a group who are looking for something, but when his cover is blown he is shot and thrown into the sea.[2]
