Carl Hollywood could not run as quickly as the nimble Nell and eventually 
lost her at a fork in the tunnels. From there he made his own judgments, and 
after some time had passed—it was impossible to know how long—his 
tunnel dovetailed with another that was carrying a stream of Drummers downward 
toward the floor of the ocean. Carl recognized some of these Drummers as former 
refugees from the beaches at Pudong.
