I love HarperCollins UK, One More Chapter, so thank you and NetGalley for this amazing advance book copy!

Would you trust your neighbor? Would you trust yours with your life?
Well a neighbor knows everything about Emily! Watched Emily.
And now Emily has gone missing! Can this neighbor find her and save her? The neighbor heard everything!

The book grips you from the start and takes you on a fast paced adventure with lots of twists and turns. It's a delicious dark, psychological thriller.

Thank you again for giving me a chance to read and review!

The Girl Upstairs is a very gripping read, but with a weak ending.

Suzie was a fascinating character, and the way she really throws herself into finding out what happened with Emily is interesting and tense.

However, the ending felt very rushed and not satisfactory to me.

Suzie lives in London almost in isolation. Heartbroken and lonely she dwells in a deep grief, her small apartment is at the same time a refuge and a damnation. Upstairs flat is a rental, and she has seen people come and go, some worse than others, but none quite as bad as Emily. Annoying noises that she makes are obviously designed to cover her loneliness.

One day the noises stop and Emily is obviously missing. Suzie becomes obsessed with Emily's dissapearance. Due to her concerns interferes to police investigation and in the process finds herself again.

Protagonist Suzie is relatable in her loneliness, anxiety and isolation which are often common in big cities. Narrative flows and the plot is complex and believable.

Fast-paced and unputdownable psychological thriller.
