Silent Parade (by Keigo Higashino)

I should have a tag just for Japanese mysteries at this point, but here we are again. Part of the "Detective Galileo" series that includes The Devotion of Suspect X. 

As usual, kept me turning the pages - and I wondered how Higashino was going to twist the ending, considering that a lot of things are known at the outset.  Is this a whodunit or a howcatchem? I thought to myself more than once. 

I wouldn't go to this as my first Higashino - I think Malice is my favorite so far - but it's another compelling, complex, satisfying mystery.
