Jeremy Sams Walkthrough Part 8
Walkthroughs For Blackwell Deception
Recovering the Periodot & The Trail of Gavin
With the Key in hand, head over to the Haines' apartment one last time. Exhaust all dialogue options with Madison. You'll be told not to come back. But that doesn't really matter. When you actually leave, immediately select the Haines' apartment as your next destination.
This time no one is home and the lights are off. When you are given options, select Use Key. This will let Rosa into the apartment. Then immediately click the bedroom door.
The Peridot necklace is on the bottom right corner of the bed. Have Rosa take it and then attempt to leave the bedroom. Madison will arrive home, trapping Rosa. The Steam Achievement Out Of Sight is unlocked if you are careful with this next part.
Please note that there is another achievement available here as well, but we recommend saving your game first. The Steam Achievement Face Plant is accomplished by following the instructions below but DO NOT have Joey blow on the Thermostat. Then Madeline won't open the door. But still send Joey through the door, and the Baby will still follow... You can likely see where this goes.
Switch to Joey and send him into the main room. Have him use his Wind power on the big Thermostat on the wall near the bedroom door. Madison will comment that it is hot and open the door on the far side of the room. Have Joey interact with the Baby. This will get the baby's attention. Next click on the doorway on the far left of the room so that he leads the baby, and therefore Madison, out of the room.
The game should switch you back to Rosa. Click on the bedroom door to have her enter the main room, then immdeiately click on the apartment door to have her leave before she can be spotted. After she exits the apartment unseen, the Steam Achievement Out Of Sight will unlock.
Take the Peridot back to Mrs. Haines. She will be pleased to have it back and will agree to put you on the trail of Gavin. The contact she gives you is a Healer/Phsychic named Lisa Tenzin.
