Tiffany Walters Walkthrough Part 4
Walkthroughs For Blackwell Deception
Rachel Abu and the Cup of Clay Cafe
When you get to the Cup of Clay Cafe talk to Rachel Abu, the woman working behind the counter. Ask her about Tiffany and she'll be surprisingly cooperative. Exhaust all dialogue options, in addition to the options from Rosa's notebook.
After the conversation, have Rosa use her phone to combine two clues. Temp Agency and STP. This will give you the location of Sterling Temp Placements.
Don't head straight over to Sterling though. Instead, head back to see Tiffany. There is one piece of information you can get from her now.
Have Joey talk to her about both Sterling and Ken. This will get you the clue that Tiffany had her contract terminated. As for Ken, about all the information that you'll get is that she was apparently quite interested in him. Now you can leave Tiffany's and head over to Sterling.
