My connections in Venice have informed me that a boat has been seen scouting for the Ottomans in Forlì, looking for a good place to invade. Kill the boat's captain. ~ Lorenzo
Wet Work was a virtual representation of one of Ezio Auditore da Firenze's genetic memories, relived by Desmond Miles in 2012 through the Animus.
Ezio Auditore received a contract from
Lorenzo de' Medici to assassinate the captain of a ship, which was sent by the Ottomans to determine the defenses of Forlì.
Ezio made his way aboard the ship and assassinated its captain, completing the contract.
The memory's name has a double meaning; "wet work" is a euphemism for assassination, with the "wetness" pertaining to spilled blood, as well as indicating Ezio's contact with water in order to reach his target.
