Who The Hell Is Hamish? is inspired by an industrious fraudster, and the group of victims who eventually decided they had had enough of him. The charming and cultured Hamish sets his sights on Bec, a recently divorced single mother with three sons and access to a significant family trust. When Bec notices gaps in his story and some odd behaviour, what starts as private unease widens into something far larger: a pattern of deception spanning continents and suspected of leaving more than $70 million in its wake.
