Inside Man: A Head Cases Novel

By: McMahon, John

Book Overview

In this sequel to McMahon's electrifying series debut, Head Cases, Gardner Camden and the PAR team return to investigate potentially connected cases.

FBI Agent Gardner Camden is an analytical genius with an affinity for puzzles. He and his squad of brilliant yet quirky agents make up the Patterns and Recognition (PAR) unit, the FBI's hidden edge, brought in for cases that no one else can solve.

PAR's latest case involves a militia group stockpiling weapons. When their confidential informant in the case is killed, it quickly becomes clear that the militia did not kill him.

As the squad looks into the evidence surrounding his murder, an unidentified man is caught on camera with their informant. This mystery man's picture is connected to another case at the FBI, an unsolved series of murdered women, buried in the ground in north Florida. Could they have uncovered a serial killer? And if so, what is his connection to their C.I.?

As PAR juggles an investigation into both the dead women and the militia, they enroll a new informant, only to find the case escalating in dangerous ways. How will PAR handle a case that increasingly looks like a terrorist plot? And in the serial case, with no puzzles or witnesses, and few leads, how will a group set up to decode riddles be successful?

Customer Reviews

PAR is at it again!

Head Cases was an impulse read because it sounded interesting and I was intrigued by the cover. So when this sequel was released, I was so eager to read it and see what Gardner and his squad of agents with quirks that made them excellent at finding the patterns of seemingly random cases and finding the culprit or culprits. It tickles my brain in a good way to see it all fall into place even as time runs down before someone dies. This book was just as much fun as Head Cases! I do like how now that this is the second book, you get to know the characters better, like Gardner with his daughter or even Richie, rookie of the group but finding his niche. I also liked how it veered a little different case wise, with the missing guns, a dead CI and then a surprise link to an older case which gives the group time to shine in their expertise of sifting through info and finding what wants to remain hidden. Lots of excitement and danger and I enjoyed the whole ride! This is a great series and I am excited to see what the PAR unit will find out next and find all the criminals that think they are so clever but are no match for these guys! I am so glad I got the chance to read this!
