Barbershop - Murdering Mason McCready | 9: Shaving Lenny Hitman: Absolution Guide
Last update: 11 May 2016
General assumptions: It would be best to eliminate Mason as a first victim, especially that he stands all the time on the courtyard near the starting place.
Mason McCready spends most of the time standing next to the barbecue located near the main entrance to the barbershop. As he us surrounded by other characters, attacking him directly is not recommended. But you should consider shooting a nearby gas cylinder. A more obvious place to shoot is the area near the starting place.
If you want to reduce the risk of detection, then a better place to shoot the gas cylinder is one of rooms on the building's floor (screen above).
Fortunately you can also get rid of Mason without risking exposing Agent 47. The first possibility in this case is swapping hot sauce. This is a multi-stage process and its consecutive steps must be done in a specific order. Start with exploring a corridor on the ground floor (the one near the main door), finding lighter fuel.
Now go to the basement and swap the hot sauce shown on the above screen with recently obtained lighter fuel.
Now just wait until McCready send one of his men for the sauce (for the first time or again). What's interesting, you do not have to do anything, just wait until using the lighter fuel will result in Mason's death. Moreover, it would be best in this case to be away from the "accident" place, to reduce the risk of detecting Agent 47 by enemies alarmed by death of their colleague.
Another option to silently eliminate Mason is electrocuting him. Explore a small alley located near the entrance to the basement (the one with interactive ledge). Pick up the wrench and detach a wire shown on the above screen. Note - decide to perform this action after making sure that no one watches you (distract enemies if needed), because you can get exposed.
After detaching the wire, approach the lever shown on the above screen and wait for Mason, who will come here to urinate. Pull it in the right moment, killing your target. After the action hide in the container or quickly walk away from this place, so you won't get exposed.
