Invisible

After successfully carrying out a highly tricky mission in Istanbul that serves to sabotage Iran’s nuclear ambitions, U.S. Army intelligence operative Paul McGrath, the hero of this superior thriller from Grant (the Cooper Devereaux series), receives a letter from his estranged father two years after it was written, thanks to the inefficient military mail system. McGrath’s choice of career alienated his father, a pacifist, but the senior McGrath offers hope for the two of them to reconcile in the letter. When McGrath finally reaches the house in Westchester he grew up in, he’s stunned to learn that his father has died, apparently from a heart attack, following a heated argument with his shady business partner, Alex Pardew. The circumstances immediately trigger guilt in McGrath over his refusal to be that partner. Things get worse when the NYPD suspect McGrath of being behind his father’s death, leading McGrath to turn investigator. Grant capably combines a riveting plot and depth of character. His best outing to date, this standalone marks Grant as a rising genre star. Agent: Richard Pine, InkWell Management. (Jan.)
