The Crescendo — John Greenwood

When execution style murders begin happening on the mega-cruise ship The Calypso, passengers and crew fear the worst. Far out at sea with no land in sight panic and chaos overtake the passengers as they fear for their lives. It is up to Adam Meluzzo, the Calypso's Head of Security to stop the killings before it's too late for not only the passengers but also the Calypso itself.
