Christie-an name? (6)
I believe the answer is:
agatha
I believe this clue is a double definition.
'christie' is the first definition.
(I've seen this in another clue)
'name?' is the second definition.
'an' is the link.
(Other definitions for agatha that I've seen before include "Wodehouse aunt" , "...... Christie, author" , "...... Christie wrote great detective stories" , "Detective story writer" , "Dame - Christie, English crime writer" .)
