Traitor is the latest in Stephen Coonts' on-going series of book starring Jake Grafton that started with Flight of the Intruder, set back during the Vietnam War. With Traitor set today that means that Grafton, by now a retired Admiral, is well into his fifties as the book opens.
Sensibly therefore, Coonts' has reenlisted the help of Tommy Carmellini, on-time thief turned intelligence agent, to whom he gave a more prominent role in his last book. Obviously realising that Grafton is now too old to be getting involved in much physical action, Coonts uses Carmellini as a surrogate to the Admiral when running, jumping or fighting is required. Grafton meanwhile remains the brains of the operation, directing the troops as the plot develops. This set-up works well, and the two leads play nicely off each other, ably supported by minor characters including Callie Grafton, Jake's wife.
Its therefore a pity that such clever use of characters to maintain a series are tied to a plot that doesn't quite past muster. Its not terrible; there are the prerequisite twists and turns and crosses and double-crosses that you would expect from an espionage thriller. There is also a nicely old-fashioned feel to events, with not to much deus ex machina reliance on whizz bang technology to save the day. Overall however, the central story doesn't really satisfy.
Its hard to explain why this is the case without revealing plot twists, but suffice to say the the motivation of the titular 'Traitor' simply doesn't feel believable. Coonts tries to provide background details to justify the person's actions but they don't ever ring true. Furthermore it is impossible to believe that the individual in question could ever have acted in the way they had for so long without discovery.
Together these are flaws in the plot undermine the rest of what is essentially an enjoyable book and left this reader feeling dissatisfied by the end. So, its a welcome return for the Jake and Tommy double act. Its just a pity that they aren't bettered served by a story worthy of their collective talents.
