Description
The first thrilling instalment in the Alexander Gregory series from globally bestselling author LJ Ross.
There's a killer inside all of us...
After an elite criminal profiling unit is shut down amidst a storm of scandal and mismanagement, only one person emerges unscathed. Forensic psychologist Doctor Alexander Gregory has a reputation for being able to step inside the darkest minds to uncover whatever secrets lie hidden there and, soon enough, he finds himself drawn into the murky world of murder investigation.
In the beautiful hills of County Mayo, Ireland, a killer is on the loose. Panic has a stranglehold on its rural community and the Garda are running out of time. Gregory has sworn to follow a quiet life but, when the call comes, can he refuse to help their desperate search for justice?
Murder and mystery are peppered with dark humour in this fast-paced thriller set amidst the spectacular Irish landscape.
Impostor is from the international bestselling author of The DCI Ryan Mysteries.
