DOOM (T1)
At the beginning you lose 7 HP due to fall damage. It's unavoidable, because you start high midair. That's why I don't count that as a ghost bust. This is a maze mission, but you just need to go up. Woman can be tricky to get, because you need to strafe run along right wall and then climb to her and go to shadow near archer. Wait for him to turn away of wall and go past him. Wait for him to look away and enter corridor.
The challenge is to sneak up while carrying body. Killing wizard is easy, but it alerts some guards below (ghost bust #1). If you reload game guards will return quietly to their positions, so maybe their alert is scripted. For more chance to succeed you need to wait for guards to come to wizard's body, then drop down and use woman's body as a cushion (you need to stand while dropping, if you drop in crouch position, dropping girl will still kill you). Exit is past guards. There is archer, so I jump twice in place to 2nd alert guards (ghost bust #2), run past them and mantle behind pillars. This means that guards will go into hunt mode (ghost bust #3). Wait for them to calm down and again use girl as a cushion. Sneak to exit.
