Thief Side Mission: Slick Willy

When you enter Willy's townhouse, you're on the upper level. There's not much to loot here, but there is more downstairs. Before heading down, examine the picture of the naked woman on the wall. Find the hidden switches, and a secrete panel opens. A dead Willy falls from the ceiling, and has an item to grab on him.

Head downstairs, and loot everything. Climb up the ladder inside the secret area, and head up. Open the chest, and grab the watch (as well as the coins). When you see the mission complete prompt, you're done.

Thief Side Mission: Taking A Fence

For this mission, you will need four arrows. Two rope, and one blunt. As always, follow the cursor until it points to a window that you can't climb to. Use focus to reveal a beam that you can shoot a rope arrow at. It may be out of range, so don't shoot yet. Instead, walk down the street to another beam. You will know you're headed the right way if there are two windows on your right, neither of which you can reach yet.

Shoot a rope arrow up to the second beam, and climb up. Open the first window, and enter the apartment. There's loot galore in there, so grab everything that you can. And no, the deer head doesn't come off the wall. Exit through the second window, and look up for a pulley. Shoot it with a blunt arrow, then shoot the beam with the second rope arrow.

Climb up the rope, and jump off at the next level. Walk to the end of the ledge, and jump across the gap to the window that you want to enter. Use focus again, and you will see a push switch on the far wall. Shoot it with your second blunt arrow, and the bars to the window open. You can now loot away. After you have everything, you get the mission complete prompt.
