Innocence is no protection… In Holloman, Connecticut, someone is preying on the innocent. At a prestigious research centre fondly known by its staff as the 'Hug', parts of a mutilated body are found. Lieutenant Carmine Delmonico of the Holloman Police learns that a string of horrifying murders – each with the same modus operandi as the one at the Hug – have been commited throughout the state. When another body is found, the medical staff become prime suspects. With the powers that be in turmoil and every member of staff hiding something, Delmonico must delve into the lives of each and every Hug employee. This is the case of his career and he is determined to solve it. But how, when he is hunting a monster who leaves no clues and is always two steps ahead? Review: On, Off - I've read every book Colleen McCullough has written, including a cookery book. I was surprised when I started On, Off to realise it was a piece of crime fiction but knowing what an intelligent writer she is I delved in. I am also a fan of crime fiction and have read a wide selection. This book was really enjoyable to read and, as I expected, well up there with the best. It seems that whatever Ms McCullough turns her hand to she never disappoints. This book deserves 5 stars. Review: Colleen McCullough - Book took a long time to come as it obviously didn’t”t come direct from desertcart. Book not as good as Colleen McCullough’s usual sagas, but enjoyed it nevertheless. ## Features - New - Mint Condition - Dispatch same day for order received before 12 noon - Guaranteed packaging - No quibbles returns ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | 2,469,481 in Books ( See Top 100 in Books ) 711 in Medical Thrillers (Books) 873 in Medical Fiction (Books) 6,630 in Psychological Fiction (Books) | | Customer Reviews | 4.2 out of 5 stars 479 Reviews | ## Images ![On, Off: A Fast-Paced Crime Novel Where the Killer Leaves No Clues - Image 1](https://m.media-amazon.com/images/I/61bz0JmbPBL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ On, Off *by J***E on 13 September 2007* I've read every book Colleen McCullough has written, including a cookery book.
