I think this is one of the best Bellairs' book I've read so far.
It's as engrossing and entertaining as usual but there's a lot of character development and plot complexity than usual.
The mystery is full of red herring and twists and turns and the solution comes as a surprise, not for the culprit but for the reason and how the murder took place.
The description of the seaside place and of the people are exception, it was like seeing a historical documentary.
It's a book I loved and I strongly recommend it.
Many thanks to Agora Books and Netgalley for this ARC, all opinions are mine.
