Please can anyone help with 39a and 23d?
39a: For the Stasi, the East German blocks file (7)
I have D - S - I - R. It looks like DOSSIER (= file), but I can’t see how the rest of it works.
23d: Key English river dredged at last, decontaminated (8)
I have - E - O - S - D
It looks like DELOUSED (= decontaminated). I can work out most of the parsing but can’t see where the L comes from.
All help gratefully received!
