"Don’t know. The tasks of Bobby Chombo, though: One, as I’ve told you, consists of listening for the Flying Dutchman of shipping containers. When he took this job, he was given a set of parameters of some kind, and this task of fishing one particular signal out of a great many others. He did it. Does it still. The container sends a signal periodically, announcing its location, and probably that it hasn’t been tampered with. It’s an intermittent signal, encrypted, and it shifts frequencies, but if you’re Bobby, evidently, you’ll know when and where to listen for it."
