Erstwhile

the premise is simple: you're a ghost, you were murdered mysteriously, and by going through the minds of the suspects you're able to unearth memories that will either clear them or convict them. the central mystery is very well-crafted; all six suspects are viable and most are interesting characters in and of themselves.

i do regret one thing, though. while the protagonist is obviously tightly focused on figuring out who just killed them, there are things he's clearly not aware of that it's possible to infer from the "red herring" evidence. while i would definitely not call the suspects' relationships "mysteries" -- honestly they're none of the protagonist's business -- since they are presented to the reader, it does feel sort of disappointing that there's no apparent way to confirm them.

it's also the case that i solved the mystery much more easily than i was expecting to just by following the obvious breadcrumbs. i felt like i was just getting warmed up when it was over. of course, "there wasn't enough of it" doesn't really count as a negative, does it?
