In this anemic medical thriller from bestseller Palmer (The Second Opinion
), former trauma surgeon Dr. Nick Garrity, who suffers from PTSD as the result of a suicide attack on his field hospital in Afghanistan, is now in charge of the Helping Hands RV, a mobile clinic that plies the streets of Baltimore offering medical aid to the homeless. Meanwhile, a high-priced hit man starts to commit a series of murders, his first victim being Belle Coates, a nurse in Charlotte, N.C. When Belle's sister, Jillian, who lives in Virginia, searches for her sister's killer, she finds a connection to Nick. Several missing homeless men lead everyone to a massive plot involving high-level politicians and a secret CIA program. The action is all fairly predictable, the characters off-the-shelf, and the writing, if not exactly purple, at least mauve: “A guttural, primal scream exploded from Nick's throat as he crouched by the body.” 250,000 first printing.
