The Posthumous Investigation

The Posthumous Investigation

Reviews
A dead man hired you to solve his own murder. You have one day. Fourteen suspects. And as many attempts as it takes. A hand-drawn noir mystery set in 1937 Rio de Janeiro, where every suspect has a life, a schedule, and something to hide.
