The Cutthroat Secrets questline in Skull and Bones sends players on an exciting treasure hunt across the open seas. This walkthrough guide will cover how to find the hidden Agent's Stash and defeat the traitor to complete the mission.

Starting Cutthroat Secrets

The Cutthroat Secrets contract is unlocked by progressing through the Sainte-Anne storyline and completing missions for the pirate kingpin John Scurlock. After enough progression, Scurlock assigns the player this lucrative quest.

Using the Treasure Map

Upon accepting Cutthroat Secrets, you receive a treasure map indicating the general location of the Agent's Stash. It mentions an outpost called the Sunken Goldmine as the hideout.

To find it, sail to the Coast of Africa region west of Sainte-Anne. Navigate the rivers to locate the Sunken Goldmine outpost on the left side of the map.

Finding the Agent's Stash

After landing at the Sunken Goldmine outpost, head inland and follow the path forward. When the path splits, always take the right fork to ascend upwards. Near the top, you will find the Agent's Stash chest beside a bonfire.

Open the stash to collect the next clue, which marks the location of the traitor you must defeat.

Locating and Sinking the Traitor

Once you unlock the traitor's location, sail to the marked area. You will find a rogue ship displaying a special icon above its health bar. Engage the traitor vessel in naval combat and sink it to complete this part of the quest.

With the traitor eliminated, you can return to Sainte-Anne and report success to Scurlock. This finishes the Cutthroat Secrets contract and grants you rewards.
