4a Smart to disconnect after energy conserved by family (5-3) _ _ _ A _ - C _ T. (final cut? if so, why?)
5d Feature of spectacular Christmas tree (5) _ _ R _ H.
The first letter of 5d is the second letter of 4a. I'm pretty sure that all the letters I have are right but if I have made a mistake the only letter it could possibly be would be the "T" in 4a.
Thank you.
