Returning from 2004's Slow Kill, stoic Sante Fe police chief Kevin Kerney receives an unexpected visit from Johnny Jordan, a childhood friend and now cantankerous former rodeo pro, who convinces Kerney to serve as a technical adviser in the shooting of a local western film. Eager for a break, Kerney heads to the location in southwestern Bootheel with his lovely wife, Army Lt. Col. Sara Brannon, and his young son, Patrick, in tow. But what starts out as a working vacation in this seventh Kerney outing quickly detours into a bloody crime scene when the body of an undercover Border Patrol agent is dumped onto Highway 81. In no time, U.S. Customs joins Kerney's investigation into a possible illegal immigrant and drug smuggling operation. Meanwhile, Sara's army job unexpectedly takes her to Ireland where she must track down and seize the notorious George Spalding, a gemstone smuggler and wartime deserter. McGarrity focuses on the details of the settings and on the characters' tactical maneuvers career- and parenting-wise. The result is slightly amplified sleuthing, deftly swapped out at surprising moments to the POV of the bad guys, and with fine but low-grade intensity.
