"Call this number and let me know where you’re staying." Skater wrote the number of a message drop he used under another name on a cocktail napkin and gave it to her. The message drop, set up like the one he was using with Kestrel, went through an answering service. Once a call was made and another password entered, the message dropped through a trapdoor in the system, where it waited to be retrieved by another passcode. For all intents and purposes, he couldn’t be made. Even the SIN he had on file with the answering service was false. Since he could call in and pick up whatever messages were recorded, it had a built-in layer of security. "If you don’t hear from me, you might want to stay lost awhile longer."
