Marvel delves into a murder mystery whodunit with implications on a vast, villainous scale

There’s a murderer at large in the Marvel Universe and it’s not the killing that has heroes in an uproar.

The death of Uatu the Watcher, long a sentinel soaking up every event that has happened, has heroes like Nick Fury, Black Widow, Thor and more seeking his killer. They’re also striving to find out who has his secrets and how they can be kept from exploding into public view for all to see.

Editor-in-chief Axel Alonso says “Original Sin” is “murder mystery” spanning from near and far, with many suspects and even more secrets.

It begins with a zero issue in April and then an eight-issue limited series in May.
