Deadly Codes by JP O’Donnell

In a small town in bourgeois Massachusetts, the wife of an NSA agent is killed by a car bomb as she starts up her husband’s car. It seems obvious that the bomb was directed at the husband, but Jennifer, the twin of the dead wife, is not so sure. She contacts a private detective, Gallagher, and tells him about her sister. She tells him what nobody else knows: the sister was having an affair with a woman; who has since disappeared. … Gallagher is fascinated. Despite having promised his new wife that he would no longer engage in detective work, he decides to take on the case and find the woman with whom the dead wife had ‘fallen in love’.

So begins Gallagher’s neat, curious, compelling hunt for an absent woman…. whose real identity uncovers treachery, treason and betrayal.
