A gripping political conspiracy thriller by Matthew FitzSimmons, first published in 2015. It is the first novel in the Gibson Vaughn series and an acclaimed debut that blends cybercrime, espionage, political intrigue, and mystery into a fast-paced, intelligent thriller.

Ten years ago, Suzanne Lombard, the fourteen-year-old daughter of powerful U.S. politician Benjamin Lombard, disappeared without a trace in one of the country's most infamous missing-person cases. The mystery has remained unsolved, becoming a national obsession.

For Gibson Vaughn, a former Marine and legendary computer hacker, Suzanne's disappearance is deeply personal—she was like a younger sister to him. Haunted by guilt and a troubled past, Gibson is recruited by the former head of Lombard's security to secretly reopen the investigation after new evidence emerges.

As Gibson follows the trail, he uncovers a maze of political corruption, powerful conspiracies, cyber espionage, and hidden agendas surrounding the Lombard family. Every revelation places him in greater danger, as influential figures will stop at nothing to ensure the truth never comes to light. With assassins, intelligence operatives, and political power brokers closing in, Gibson must rely on his military training, hacking expertise, and instincts to survive.

Packed with sharp dialogue, memorable characters, and relentless pacing, The Short Drop delivers numerous twists while exploring themes of loyalty, betrayal, political ambition, and the consequences of long-buried secrets. It has been widely praised as one of the strongest thriller debuts of the past decade.
