I've always liked it a lot, and would have seriously considered it IRL if only I had a different ln.
On the other hand, I really can't see the point of
Henrietta! Clumsy and much too long, with the potential for really trite nns.
Harriet doesn't need a nn, IMO.
I've always dithered between
Daisy Harriet and
Harriet Daisy. Once again, it's down to the ln I think.
And then of course there's the
Dorothy L Sayers character: one of the most well-rounded women in detective fiction, and all fiction actually.
