Anubis Airlines from Club Dead : Bill Compton's coffin is stolen

Bk 3

"As Russell Edgington's people tell it, .. The humans responsible for taking her coffin to the airport took Bill's identical coffin by mistake. When they delivered the coffin to the hangar Anubis Airlines leases, they left it unguarded for perhaps ten minutes while they were filling out paperwork.
During that time-they claim-someone wheeled the coffin, which was on a kind of gurney, out of the back of the hangar, loaded it onto a truck, and drove away."

"Someone who could penetrate Anubis security," I said, doubt heavy in my voice. Anubis Airlines had been established to transport vampires safely both day and night, and their guarantee of heavy security to guard the coffins of sleeping vampires was their big calling card. Of course, vampires don't have to sleep in coffins, but it sure is easy to ship them that way.
There had been unfortunate "accidents" when vampires had tried to fly Delta.
Some fanatic had gotten in the baggage hold and hacked open a couple of coffins with an ax. Northwest had suffered the same problem. Saving money suddenly didn't seem so attractive to the undead, who now flew Anubis almost exclusively.
"I'm thinking that someone could have mingled with Edgington's people, someone the Anubis employees thought was Edgington's, and Edgington's people thought belonged to Anubis. He could have wheeled Bill out as Edgington's people left, and the guards would be none the wiser."

"The Anubis people wouldn't ask to see papers? On a departing coffin?"
'They say they did see papers, Betty Jo Pickard's. She was on her way to Missouri to negotiate a trade agreement with the vampires of St. Louis."
."There was also extra confusion at the time," Pam was saying. "A fire started under the tail of another Anubis plane, and the guards were distracted."
