Private Investigator Alexandra Best has been hired for a missing persons case. The question is… is the victim even missing at all?

Thirty-something Caroline Price has been ‘missing’ for over two weeks. A reclusive freelancer, Caroline rarely has plans, rarely speaks to her family, and rarely leaves her home. But, surely, this doesn’t mean she’s been the victim of foul play. What’s more suspicious is why has her father waited until now to begin an investigation. And why doesn’t he want the police involved?

With a large inheritance at stake and a greedy cousin second in line, Alex isn’t so sure that something terrible hasn’t happened after all. And when Alex finally finds a clue in Caroline’s diary, it brings more questions than answers. Who is this mysterious ‘M’ who features so heavily in Caroline’s entries?

With more suspects than she can keep track of, Alex might be in deeper than she realises. Can she find Caroline before her own life is put at risk?

The first in the Alexandra Best series, this page-turner is a fast-paced mystery that will have readers racing to the end.
