'It's not me then?' she says. A little bit of my heart breaks, and I struggle to swallow down the lump in my throat. 'No Jane, it's not you. You were right.'
Why won't he ever let you use his phone? Why is he always going on about that girl from work? Is he cheating on you?
There's one way to find out - ask him. Then (when he lies) call Rebecca Jane, founder and owner of the Lady Detective Agency.
The Agency is one of the UK's most successful female private detective services. It exists for one purpose: to find the truth.
Whether that means trailing a transsexual prostitute through the streets of London, following suspected cheats on stag parties, tracking down someone's beloved pet ferret or uncovering famous people's affairs, Rebecca and her elite team will help. Whatever it takes.
Their extraordinary dedication stems from first-hand experience of deception. Here Rebecca not only reveals her clients' fascinating stories, but her own rollercoaster journey too - from early success to crushing failure, scandal, abuse and affairs, and ultimately to finding true love.
At times heartbreaking, hilarious and eye-opening, this vibrantly-written compilation of stories introduces us to a sparkling and witty new voice in Rebecca and her crack team of female detectives who are always ready to solve any case, no matter how big or small.
For the first time, the Agency is opening its doors and revealing its secrets.
Guilty consciences beware.
