Find the shooter.
With her suspect shot dead, Aveline ascended to the rooftops to find clues left behind by the shooter.
Following a trail of clues, Aveline happened upon another trace of evidence near the docks, when she was suddenly shot at. Chasing the assailant, she killed him with the Hidden Blade and looted his corpse, discovering a letter.
- Letter: When you are finished cleaning in New Orleans, come to the bayou. We'll gather near the deserted garden. We have the other witness. Hurry if you want to interrogate him as we need to get rid of everything that could expose our plans.
Aveline found out the two murders she'd discovered were part of a larger plot.
