Do No Harm

4.5★s

Do No Harm is the third book in the Lucas Page series by Canadian author, Robert Pobi. Only brilliant astrophysicist and numbers genius, Lucas Page could come home from a charity dinner convinced that thirty doctors have been murdered undetected by any law enforcement body. By the next morning, his grad student Bobby Nadeel has analysed the cases and produces the figures to prove it, but FBI Special Agent in Charge of Manhattan, Brett Kehoe isn't wholly persuaded that this string of accidents, suicides and seemingly natural deaths are really murders.

When their friend, Dr Dove Knox has apparently suicided after the same dinner, Lucas's wife, Erin asks him to look into her colleague's death. Much to the irritation of the NYPD and the ME's officers, Lucas immediately reads the scene as murder. By the time Dr Arna Solomon is shot in what is meant to look like a mugging in the car park opposite Weill Cornell, the FBI is convinced.

As first responder to several of the cases for which the FBI is requesting files, NYPD Detective Johnny Russo has quickly worked out that something is going on, and demands to be involved. The irritating alcoholic does seem to have some valid points, and seems able to withstand his rudeness like water off a duck's back, so Lucas reluctantly lets him stay.

Thorough investigation and analysis lead them to conclude that the murders look random and, indeed, the victims seem to have nothing in common except that they are doctors; of the few cases where a perpetrator is identified, nothing seems to link these unlikeliest of killers to their victims. Their motivation to commit murder is a complete mystery.

Any inclination Lucas might have to leave the investigation to the FBI, though, is quashed when Erin is targeted by a gunman and three of their children narrowly escape incineration. The FBI goes into deep analysis of every scrap of data they can find, and gradually, Lucas forms a theory.

Despite the red herrings and distractions, the most astute reader may figure out what is going on early in the piece but discovering the who, the why and the how is guaranteed to keep the pages turning right up to the final jaw-dropping reveal. And whenever the tension builds up, Russo throws in his two cents worth, or there's another vehicle mishap…

Special Agent Alice Whitaker, somewhat recovered from the injuries sustained in their last encounter, ends up needing her shiny black Navigator SUV replaced FOUR times as she drives Lucas around, courtesy a wild mercy run to hospital, a body falling from a great height, a motorcyclist through the rear screen, and a second body falling from a great height. And then a Ferrari SF90 Whitaker is driving is comprehensively destroyed in an exciting high-speed car chase.

This third instalment is cleverly plotted and Pobi includes plenty of action scenes, some of them quite grisly, characters from previous books engaging in entertaining dialogue, some chillingly nasty killers and a high body count. Disbelief may need to be suspended for some aspects, but the best advice is to hang on and enjoy the ride. Gripping, intriguing, and often blackly funny, this is another excellent crime thriller.
