A brilliant engaging storyline with twists and turns all the way through. The characters- especially the twins - are fabulous, their relationships constantly evolving and pulling in the reader.
A great story for all to enjoy.

When they go with their art restorer mother to a job in the middle of the countryside, the Morrow twins are expecting boredom and isolation. They get neither, as they are drawn into he houses many mysteries, most importantly finding what happened to a woman who went missing from the house over ten years ago. With Harrison's usual flair, she adds "a pinch of magic" to this new novel which I think will be loved by Key Stage 2 children (I can think of several of my Year 7s who would love it, too).

When Meredith and Rose (aka Merry and Spike) travel with their mother on one of her assignments to a house in the countryside, they have no idea of the adventure that awaits them. In addition to the reclusive owner, the place holds any number of secrets - including the story of a missing woman.

But Merry and Spike, identical twins with quite different personalities, have a few secrets of their own. Not least the mystery of what happens to the very nature of time itself when the twins are around...

This excellent story involves mystery, magic and mayhem (sometimes unintentional, though Spike can be a bit of a troublemaker!), with plenty to keep the reader engrossed. This is creative storytelling that will fire the imaginations of children in the target group. An enjoyable read. It gets 3.5 stars.

I thoroughly enjoyed the premise of this book - the combination of magic, mystery and adventure will really appeal to young readers. I thought the start was exceptionally strong and I was immediately intrigued. It’s set in a creepy old manor house and is suspense-filled and action-packed from the opening. I thought the ending was a strange combination of being incredible far-fetched whilst also being predictable: I felt the story telling was better than the story in this instance. I’m sure it will be enjoyed by young readers however.

A thrilling time-hopping murder mystery !

This story reads a bit like an Agatha Christie book : there's an old manor house, an elderly lady with quite a fortune, employers and family members who could all have motives to commit a crime. In addition, the magic brings an original twist and leads to more suspense and mystery.

The plot is well-paced and the mystery well constructed. I hope this is the start of a series, as I'd love to join the Morrow twins on a next investigation!

Many thanks to Simon and Shuster, as well as NetGalley for the ARC. This is my honest opinion of the book. Review available now on Goodreads and on retailer sites after publication date.
