Most readers won't know the name John Ramsey Miller, nor are they likely to have heard of Inside Out, which is a tremendous shame because this is a fantastic action thriller.
The summary sounds like well worn material: several U.S. Marshals, including the novel's protagonist, Deputy Marshal Winter Massey (who reminded me of Martin Riggs from Lethal Weapon at times), are tasked with protecting a sociopathic hitman and his wife at a classified safehouse so the hitman can testify against a mafia boss. Obviously all hell breaks loose, bullets fly, marshals and assassins die, and Winter wants justice and revenge in equal servings.
However, that's the very tip of the iceberg.
Without giving too terribly much away, what initially seems to be a standard witness protection action thriller romp, akin to Eraser and Safe House, shifts into territory evocative of Three Days of the Condor, which came as a pleasant surprise. This isn't Eraser, with the hero slaughtering half the planet while they protect the witness from frequent hails of gunfire and explosions the entire time, its something else entirely.
The foot never comes off the gas: this is a brisk, taut book with a good quantity of bloody gunplay and close-quarters combat that never skimps on the gory details. One particular character has several lines of literally laugh-out-loud funny taunts, that I just couldn't help but imagine being played by Wilford Brimley, had Inside Out existed, and been adapted, in his heyday.
I'm looking forward to reading the second book in the series in the near future.
