I'm so glad they got rid of the pdf guides. The format was always so disappointing, and somehow the guides were less helpful that their html counterparts.

Sidquest: Cloak and Daggers
After finishing inside the police station, you'll get a page from Jenny Alexander. She is working undercover as a hooker and wants your help in catching one Jack O'Malley. To do this, you'll be posing as an assassin for hire.

Meet O'Malley behind the police station (Where the locker from Motherly Ties was) and bluff with him that you'll take out Double-T. For this mission he will want you to gain a specific weapon, a crossbow to do in the gangster.

Head to the western entrance of Derelict Row and arm yourself with the gun (It takes up a lot of space, so make sure you have room). While you're hear head into the Row itself. You'll gain more rewards from sneaking, but can still complete the quest if you're caught.

On the second level of the hideout in the north-east will be a hole in the ground. Drop down this hole to find the hidden chance of weapons which will help Jenny in her case.
With these two pieces of evidence, head to Double-T's apartment. Including Double-T, there are six enemies: one guarding the door, one in the kitchen, two watching TV, and two in the locked room. Due to the small space and volume of enemies, it's better to use silent takedowns than kill any of them.
Once the first four are down, either hack the locked door or fire an audible shot to bring Double-T out. Make sure to use a stun gun or silent takedown to detain Double-T. Exit out this apartment and head into O'Malley's place (The same home as Brian Tindall).

You'll need to either gain the passcode behind the bookshelf (code 1029) or hack through the doors to find O'Malley's stash. However, his room is trapped with mines. Grab on of the cardboard boxes and toss it into the room to detonate the explosives. Once it's safe, explore the bed room for more evidence and clues.

Return to Jenny with everything you've uncovered and she will ask you to bring in O'Malley. Head back to O'Malley's apartment and use a non-lethal takedown. Report back to Jenny to complete the mission.
