The premise of this book is an interesting one but it falls flat in certain areas. It’s a short novella so maybe this is why it doesn’t quite fulfil its promise.
It would certainly appeal to the YA market and has a feel of R L Stine and Christopher Pike books. There is certainly a great deal of suspense in the opening chapters of the book and the doorbell and 3.33 time element was intriguing.
The plot became a little disjointed in the second half and some of the references, such as the nod to one particular book on the detective’s shelf which later became part of the tale felt a little forced.
That said, there is enough suspense to make you want to finish the story to find out how it all links together and the cliffhanger ending when you think everything has been resolved is perfect.
