If the Doctor...
Actually WAS the murderer, then how do you account for him banging that one woman after the party, (where he was for a very long time) and seemingly was NOT alone that entire night until after he went to his ex-wife's and found his lover's body??? He was either 1) at the party with many others when his wife's lover was killed or 2) with that woman he had sex with afterwards, no???
