Home from the Party — Robert MacLean

When a key player and high roller in a game of sinister political deals is murdered, Athens sends out Captain Kosta Konstantinou, a Canadian-educated idealist, to investigate. On the island of Nostas, he finds among the artists, celebrities, pushers and gigolos, a tangle of connections -- with the former dictatorship, with the CIA, and with each other. Through parties and police files, truth serum and seances, Kosta stalks his killer -- in the growing knowledge that he must succeed if he is to save the new order, and himself.
