where do becky and miles go at the end of chapter 1

Dr. Mile Bennell and his one-time girlfriend Becky Driscoll are called to visit their friends Jack and Theodora Belicec. Seems that the Belicecs are not busy cheating at football, but are instead trying to figure out what is the deal with a half-formed body on their billiards table. The body is not just unformed, but doesn’t even possess fingerprints. As they try to figure out what to do about it, Theodora screams that it is Jack. Sure enough, the body is taking shape and the form is going to look just like Jack.
