This is the sort of conversation that can only end in a burp.

Sandra and her husband Striper are remorseless serial killers who have each eaten at least fifty people. They haven't been caught due to a series of rules they set for themselves. Some of them are:

• Only eat people who won't be readily missed (hitchhikers, temporary workers, the homeless, that sort of thing). Their city of residence, Anchorage, was chosen due to its high number of seasonal workers and other potential victims.

• NO TROPHIES. Keep nothing. Burn anything your prey had that might be identifiable. This includes any money or credit cards they had. Generic clothing can be dumped in Salvation Army bins once it's checked for monograms or other ID.

• "Who"? They intentionally avoid learning their victim's names and don't eat people they personally know. There are rare exceptions. Sandra has eaten a couple of fellow exotic dancers, for example, but strippers/dancers tend to come and go from dance clubs and go and she chooses her prey carefully.

• Know the enemy. Sandra has a part time job as a clerk at a police station and Striper works as a security guard. They spend a good deal of time watching cold case file shows and their jobs keep them in the know regarding police forensics.

Almost all of their prey are humans, anthropomorphs being extremely rare in their setting, but not everyone likes human prey so tonight Sandra gets a nice filling hyena. 83
