Journalist Wells or Tarbell
I believe the answer is:
ida
I believe this clue is a double definition.
'journalist wells' is the first definition.
(I've seen this in another clue)
'tarbell' is the second definition.
(I've seen this in another clue)
(Other definitions for ida that I've seen before include "- Rubinstein, Russian dancer, actress" , "lady" , "Greek mount - Gilbertian princess" , "Cretan mountain - Gilbert and Sullivan princess" , "Princess __ (G&S comic opera)" .)
