Only this time the victim turns out to be his mistress, with whom he broke up quite recently.

Moreover, Liam himself has absolutely no memory of what he did or who he was with on the night of the murder. In a panic, he turns to his brother Sean, a homicide detective. But even he is unable to cover his brother. Absolutely everything points to Liam, from fingerprints to DNA tests. Now the former forensic scientist is forced not only to go into hiding, but also to compete with his colleagues to uncover the truth. The truth about your own past.
