Janet, how it this considered "slush" if you requested his manuscript? If a book that goes through the query/manuscript request/agent sale process is considered slush, then what is not considered slush?
Patrick Lee arrived via query letter in my slush pile.
Slush refers only to incoming queries. Almost every query I get is "slush" in that I didn't ask for the query to be sent to me. And that's fine with me. I love slush. I love my queries.
Patrick Lee was NOT in the slush pile at Harper. Nosirreebob he was not. He was in the requested manuscript stack because I called the editor, pitched her, and she's not an idiot.
What I mean by the phrase "slush works" is that sending a good query with good pages will get you the attention of an agent. You don't need anything more than that if you write compelling fiction.
