Hey, I was right. There /was/ a rejection letter in yesterday's mail (from St. Martin's, on Heart of Stone). It's just that the mail got there very late, so I didn't find it until this morning when I went out to put some bills in the mail.
Total form letter. Dear Sir/Madam. You know, if wanna-be authors sent Dear Sir/Madam letters to publishing houses, they'd get docked points for it.
OTOH, wanna-be authors don't have to deal with five thousand unsolicited submissions a year.
