Alex gets taken to the doctor more often that Alex likes. Dr White takes an awful lot of blood samples – so greedy is he for blood that he uses a double syringe and he sends great big bottles of if to the ‘lab’. This makes Alex suspicious – and sure enough, the blood ‘samples’ are not going to a lab at all, but to the blood bank. Alex decides to investigate, and it turns out that the blood bank has been taken over by flocks of white-coated vampires!
