Daily chess puzzle: Check Mate # 460

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.  
White to play and mate Black. 

Friker v De Vila, Catanzaro 1979
Solution 
A nice one today, used some geometry. 1 Bb7+! deflects the black queen to b7, so that 2 Qe8+ forces 2…Ka7
Then 3 Bd4+ wins the Queen, and at the end the LPDO Ne1 drops off.
