A Bay Of Blood - 1971 - 7/10
AKA - Reazione a catena

An elderly lady is noosed from her wheelchair and left dangling.
The assassin emerges from shadows and is himself slain.
Next, greedy and murderous heirs begin to migrate to the bay manor.
And blood flows and flows.
This ain’t high art but it is an excellent Giallo by Bava.
Film is packed with killings and attractive females.
If you anticipate swim sequences and couplings, so did Bava.
Often hard to keep track of who is killing who - I mean that as a plus.

Be sure to check out insightful audio commentary by Bava biographer Tim Lucas.
