X Marks the Spot — Mack Thornton

Marked for death! Private Investigator Timothy Jarrett can never resist coming to the aid of a damsel in distress, especially the young attractive ones. But when he agrees to take the case of the charming Miss Megan Marks, he gets much more than he bargains for. The girl turns out to be not only the granddaughter of notorious gangster Shorty Simpkins, but Megan has a map to Shorty's hidden gold that her crooked Uncle Harry is willing to kill for. Every gangster in the city gets involved in the case, but are they interested in helping the girl or finding the treasure for themselves? Jarrett knows Uncle Harry will never give up so long as his niece is alive. The private eye finds himself in a desperate race against time to discover the location of Shorty's hidden gold before Harry can carry out his death threat against his young client. X Marks the Spot is the sixth book in the Timothy Jarrett mystery series.
