Miss Snark -
Just read your recent post on query letters and your advice to send five pages of your writing.
But what if the agent specifies that they want query letters only, or you're sending to someone like Kristin Nelson who only wants emailed queries? Do you stick the five pages in the body of the email? Do you ignore the agent's rules about sending a query letter only?
I have no idea how my colleagues who only read cover letters get a sense of the writing but they do so maybe they have extra smarts that Miss Snark doesn't. Half the partials I read are from stupid query letters..and the partials are pretty darn good.
Anyway, the answer is: if an agent says cover letter only, only send the cover letter.
Under NO circumstances would you send an attachment in an e-query unless asked to do so.
That's just inta-delete these days.
