Deadlocked is a 2012 urban fantasy novel by American author Charlaine Harris and is the twelfth and penultimate book in her The Southern Vampire Mysteries.

A dead woman is found on the lawn of Eric's house while he is having a party in honor of Felipe, embroiling Sookie and her vampire friends in a police investigation.

Meanwhile, Sookie's fairy great-grandfather, Niall, visits in order to investigate who placed a spell on his son, Dermot, to make him mad.

She catches him feeding on the woman who is soon found dead on his lawn, and who was laced in fairy blood and was purposely sent to Eric in an attempt to frame him and for Sookie to find out; she has to contend with the final command of his maker, Appius Livius Ocella, for Eric to marry Freyda, Vampire Queen of Oklahoma.
