A Poisonous Echo - Mai Griffin

Joyce is angry that her boss won't leave his wife, so his wife will have to be removed... one way or another!
A poisoning is planned and Joyce sets out to leave a lasting impression... then Joyce goes missing... A malevolent ghost and psychic detectives form the core of this enjoyable stand-alone sequel to Mai Griffin's Ghostly Echoes.

Originally published as A Poisonous Shade of Grey, the second of the ORIGINAL Shades of Grey series – long before any of a number of other Shades of Grey were published by other people, this book is a Ghost Story – with little or no sadomasochism in its content! Well, to be precise, it hasn’t any! We, the publishers and the Author, give up. Our books came first – our titles were out first – our books are beautifully written and crafted – and we are fed-up with the assumption that this series is in some way a spinoff from any other when, in fact – we repeat – it was written and published FIRST!
In whatever order you read her books, Mai Griffin’s series of supernatural thrillers, Ghostly Echoes, will grip you.
