5d 14 may have 27 in his hand! (7) L--U-R-
The u could be wrong: it comes from 13a wholesome whole sum which i decided was truth. Now I think it could be total and 5d could be letters??
10d 1500 metres athlete of the past (5) --H-R
Again, depending on 13a, this could be --L-R either
12a Thoughts even initially said wrong (5) --E-S
35a It lies-and lies not- within indolence (4) D-L-
This looks like "dole" but why would that be right, if indeed it is?!!
