Mykonos After Midnight - Jeffrey Siger

Mykonos holds tight to its past even as it transforms from an obscure, impoverished Aegean island into a tourist mecca and summertime playground for the world's rich, a process making the Mykonian people some of the wealthiest in Greece. Yes, the old guard is still a force to be reckoned with despite the new money.
One of them, a legendary nightclub owner, has been found savagely bludgeoned in his home. All evidence points to obvious thugs. Yet the murder has put long hidden, politically explosive secrets in play and drawn a dangerous foreign investor to the island paradise. Andreas Kaldis, feared head of Greece's special crimes division, is certain there's a far more complex solution to the murder than robbery, and he vows to find it.
His quest for answers cuts straight into the entrenched cultural contradictions that give Mykonos so much of its magic and soon has him battling ruthless opportunists preying on his country's weakened financial condition. Kaldis learns there is a high, unexpected price to pay for his curiosity as he becomes locked in a war with a powerful, clandestine international force willing to do whatever it takes to change and wrest control of Mykonos, no matter the collateral damage. Such is global crime. And the need for a wily hero to stand against it.
