Charlie's Angels

I just called the library to make sure they actually had a book on the shelf - the web catalogue says yes, but you never know. I wanted to save myself a walk in case it wasn't there, especially since it's book two of a series and that will drive me crazy.

The elderly-sounding woman who answered the phone said she couldn't hear me very well, so she asked me to spell the last name of the author. No problem, it's only four letters.
"Cast," I said. "C - A - S - T."

"P?"
"No. C for Charlie, A for....... Apple, S for Sam, T for Tango."

A is Alpha but I forgot, and it was so natural to say Angel after Charlie... but I resisted.
