While Trey put a better gag in the assassin's mouth and beat him black and blue in the bathroom, Tristan went to the living room to check out the phone found in the man's things.
It was a model with buttons and minimum of functions, so Tristan wasn't hoping for much. However, it was still locked with a password, so there had to be something.
Being an expert hacker thanks to his system, Tristan knew from a single glance how to bypass the password.
He just looked up the master-code for that model of phones, and in ten minutes, scrolled through the history of the assassin's calls.
All of his contacts were named something like "Useful guy" or "always asks for money". There weren't many contacts in the first place, and no text messages in the archive. The history showed a few recent calls, but none that happened while Tristan was in the Urban Mirage Club.
This was obviously a burner phone.
