When I first walked into Jake and Megan’s immaculate home, I felt totally at ease. Sitting in the crisp white living room, they held hands and talked lovingly about their baby girl, Fern. As the weeks passed, I began to think I’d made a mistake in taking the job.

And Megan seemed to take pleasure in telling me off in front of her husband, blaming me for things I hadn’t done.
