this was... okay, but a huge disappointment after the Truly Devious Trilogy.

Johnson made Stevie dream of being like Hercule Poirot, but the foreshadowing fell flat with the 'grand reveal'. The point of Agatha Christie's mysteries is that all of the information is available to the reader before Poirot reveals his solution, but since the solution depended on Sabrina's diary which was only revealed in the 'grand reveal' itself, there was no way the reader could have tried solving the mystery themselves and that automatically takes off half of the fun in reading murder mysteries. Also making the killer a literal Nazi is sooo unoriginal and overused — I am no Nazi sympathizer (!!) but I've seen this so many times in all types of American media that you just can't surprise me with that anymore.

I was mostly annoyed with how the mystery was executed, but as a cherry on top I couldn't care less about Stevie and David's relationship either — I don't see what they are supposed to see in each other, and in my opinion Stevie is perfectly capable of being a strong female YA protagonist without having a love interest.
