The King's Collar (en Inglés) - Jeff Tanner

Boston, May 1929. Expelled from Harvard and disowned by his father, Charlie Bohannon is down to his last nickel when he stumbles across a chance at salvation: a priceless Egyptian statuette hiding in the smoky recesses of a speakeasy. Learning it was stolen from a long-ago expedition led by his college dean, he sees returning it as his only shot at redemption-but the plan shatters when the artifact is stolen and the thief is murdered.

From the corrupt halls of power where Joseph Kennedy pulls the strings to the seedy docks of the Atlantic, Charlie suddenly finds himself in the crosshairs of several dangerous men. They don't just want the statue; they want its legendary counterpart: the jewel-encrusted King's Collar. They think Charlie can find it. And they'll happily kill for it.

Aided in his quest to find the King's Collar by daring socialite Olivia and salty ex-sailor Punchy, Charlie plunges into a shadow-game where killers hide in plain sight. When his friends are kidnapped, the hunt for the Collar becomes a race against time. In the cutthroat world of the Prohibition era, Charlie must find the treasure-or pay for it with their lives.
