7D Devotee(?)

[CrikeyMoses]

Hi
Like many others here I'm pathologically unable to post any prize crossword unless I can parse all the answers!
7D Fan letter opened by X
D_V_T_E is almost certainly devotee, 'fan', but I cannot work out why and it's driving me mad.
Hope someone can point out what's probably obvious!

I would say Dee is the letter, vote is the X.

[CrikeyMoses]

Ah, thank you. I pondered dee as a letter but I couldn't convince myself. Didn't see vote as X - obvious, really.
This was the Sunday Times 4557 by the way - I did put the details in the drop down box, but it didn't show.
Thanks again.

Letter= dee
X= vote

Ta. I've only ever seen 'dee' as river/flower before, but the dictionary confirms that 'dee' represents the letter D; I guess most other letters aren't usually transcribed phonetically, although em, en and ell are all measures and turn up fairly often.
