Girl in the Blue Coat

Story : Hanneke needs to find a girl that disappeared in WWII. I really liked the plot, but the last 100-50 are so confusing and the ,,plot twists” are so predictable. I thought this will be Sherlock Holmes, but Hannake's version, and it is, kinda. There are some amazing intense scenes that give you goosebumps, but it kinda feels useless.
Characters : Hanneke is okay and her past didn't really interest me. The most interesting characters are her friends: Ollie, Judith etc. They work on something and it's so intriguing to see how they plan everything.
Overall : Gripping plot, but falls apart towards the end and I couldn't get attached to Hanneke... I was more interested in Ollie, lol.
