Million Dollar Lover is an unlikely love story, recorded in real time as the relationship unfolds between Carolyn, who is 80 and has properties worth a few million dollars, and Dave, 57, a former drug addict who is homeless and has spent a decade in jail.

The story captured the attention of the BBC Journalist Sue Mitchell, as it was unfolding on her street. She spends a lot of time in California – she married an American and her award-winning journalism has been about the lives of people like Dave who inhabit the dangerous margins of society.

There are so many homeless people in America that the wealthy can no longer avoid contact with them. When Dave arrives in Cayucos, a charming beach town, prosperous and sunny all year round, he goes to church. Some people there try to help him find work and recommend him to Carolyn as an odd job man. She falls in love with him and within a fortnight, Dave has moved in.

Dave is a talented man – a skilled joiner and musician who makes and sells jewellery. With Carolyn’s support, he is ambitions for his future. He appears to be thriving and so does she. But she is vulnerable following the death of her husband. Her family fear she is showing signs of cognitive decline and she certainly struggles to manage her finances. She also yearns to feel the love that comes from a romantic relationship and to feel needed again.

Her neighbour, Marie, says it is something she sees a lot amongst the elderly people she cares for; it is a desire to be loved and to be in love which does not diminish with age. Marie cautions Carolyn against rushing into a relationship with Dave, but it is too late. Soon Marie is left watching from the side-lines as Carolyn starts cutting off friends and relatives who question her.

Her middle-aged daughters are increasingly worried for their Mum and for the money they expected to inherit from her; a property portfolio which their parents and grandparents had built up over the years. They fear Dave might be taking advantage of Carolyn and ask her to be assessed for mental incapacity: it seems the only explanation they can find for why she has fallen so deeply under his spell.

Sue Michell is a skilled investigator who uncovers horrors in Dave’s past that he has never mentioned to a living soul. She also brings her knowledge of elder abuse and exposes how the process of ageing makes subtle changes that can alter how we see others - particularly strangers who seem loving, young, and strong.

Is Dave really a tender carer who will cherish Carolyn to the end as he promises, or is he a dangerous interloper who will fleece Carolyn – breaking her heart and her family?
