A former postal inspector, Mercury Carter specializes in moving sensitive or dangerous packages from point A to B. And sometimes he needs his gun to do so. Carter’s current mission leads him to Providence, Rhode Island, but his delivery is interrupted when he comes across a woman badly injured in a car wreck in the pouring rain. Then a man with a gun appears warning Carter away from the scene and Carter leaps into action, disarming the attacker and rescuing the crash victim. Just as Carter thinks the danger has passed, he discovers a deeper mystery stemming from the crash, a deadly puzzle involving a memorable pair of grifters, a crooked ex-cop, stolen identities, human trafficking and murder. And it appears that Carter’s next assignment will put him right in this conspiracy’s perilous center.

Mercury Carter is a deliveryman who takes his job very seriously. When a parcel is under his care, he will stop at nothing to deliver it directly to its intended recipient. Not even, as in the current case, when he finds a crew of violent men at the indicated address who threaten his life and take the woman who lives there hostage. That’s because Carter has special skills from his former life as a federal agent with the postal inspection service. After Carter dispatches the goons sent to kill him, he enters a home besieged by criminals --- but the leader of the gang escapes with attorney Rachel Stanfield before the mailman can complete his assignment. With Rachel’s husband, Glenn, in tow, Carter takes off in pursuit of the kidnapper and his quarry. Along the way, he slowly picks off members of the crew and uncovers a far-reaching conspiracy and a powerful crime syndicate.

After years of personal and professional turmoil, things are finally looking up for Columbus, Ohio, private eye Andy Hayes. As SICK TO DEATH opens, Andy is relishing his new gig: a drama-free, family-friendly stint as a guard at the Columbus Museum of Art. However, Andy’s newfound equilibrium comes crashing down when he interrupts the theft of a painting by famed Ashcan school realist George Bellows --- and is promptly fired for breaking museum protocols. Helping him thwart the robbers is Alex Rutledge, the adult daughter he never knew he had, the result of a one-night stand during his misspent youth a quarter century earlier. Alex wants to hire her newly discovered father to find the driver who killed her mother five months earlier in a still unsolved hit-skip accident.
