Can anyone help with the parsing of these three clues? I have the answers but I'm still missing a couple of names and one extra letter so they might be in these ....
5a - Greek character keeps a hearse in hospital (7) S????AN
The answer has a 3 letter "hospital" as the 1st, 6th and 7th letters but I just cannot see how P??T comes from the rest.
37a - Greene, Kafka, regularly smoke (4) R??K
Assuming the answer ends in K then it looks like alternate letters of "Greene" but why K from Kafka?
41 - Charges Oberon and Titania? (4) F??S
My answer is a word meaning "charges" as in 'costs' but haven't the slightest idea why?
