I know what I saw...

'The ghosts of today live not in castles or stately homes, but in ordinary houses and offices, and they're witnessed by ordinary people like you and me. We just need to figure out what the hell they are - the dead returning from the "undiscovered country" of death? Or the product of that equally mysterious and ancient location, the human mind?

This book is the story of these ordinary people who have experienced extraordinary things and want to make sense of them. Each one is a brand-new case I have never shared before; modern day ghost stories that make my blood run cold as effectively as anything that Charles Dickens could rustle up. And they are all entirely true.

It's also a story of my own personal journey of discovery because I've realised something while reading all these incredible stories that come my way. I've realised how much I want to believe. I'm asking you to join me, to keep an open mind and to prepare to have your very concept of reality challenged. Are you ready?'
