Victoria Strauss said: That was George and Janet's M.O.
Yup; and long after Janet Kay and her husband were dragged off by law enforcement personnel, publishers are still getting submissions from their agency. Nobody's told their authors to stop sending out submissions under the agency's name. Scam agents never do anything for their clients, but George and Janet took "not doing anything" to new heights. They had a few form letters, which they used over and over again. The authors did all the work.
Another feature of G&J's M.O. was that they never read the manuscripts. Last I heard, their local jail had a locked cell full of evidence that had been seized during the bust: some vast number of submissions in envelopes which had never been opened. Reading is work. Opening and logging envelopes is work. George and Janet didn't do that.
Desert Rose is located in San Angelo, the same small Texas town that Janet and George Kay worked out of. It opened for business shortly after they got busted. It uses many of the highly idiosyncratic methods they always used. It's more than reasonable to assume that Leann Murphy got her training from Janet Kay et al., and is continuing her business.
If so, she doesn't know squat about books, bookselling, agenting, or publishing, and she's never seen a manuscript sold to a legit publisher. She's learned a scam method where you never read the author's work. I doubt you're ever going to get to see that "query" she talked about, because it would have contained specific references to your book's content. Finally, the reason you're being asked for a synopsis is that she can't possibly write one.
I don't care what it says in your contract with Desert Rose. Send Leann Murphy a letter saying that unless you hear from her, immediately and in a satisfactory fashion, you're terminating the relationship. Give her a near-future cutoff date. Tell her you'll have the law on her if she tries to fight this. She may threaten you, but she won't actually fight you.
