Morgan Pendleton is one of two brothers that you must deal with in Mission 3: House of Pleasure. Morgan resides in the steam room of the Golden Cat, which is located on the bottom level. Make your way to the steam room (it will be marked on your screen). Descend the stairs, and straight ahead you should notice a vent a little higher up. Blink up to it and crawl through to the other side. In here you will find a red turn wheel, pick it up using , and then attach it to the pipe by pressing again. The wheel can now be turned, and doing so will fill the room with hot steam. Keep turning the wheel by holding down until the steam kills Morgan Pendleton, at which point this trophy will unlock.
