This rating would be an 8 but that I'm not really keen on one particular plot device. It wasn't over-used but I think the piece would have wrapped up better if it had been left out.
Temporary guests had a tiny but darkly entertaining role. They could have been made better of, and maybe were abandoned on the cutting room floor.
Family dysfunction and quasi-redemption dominate, old secrets are brought to light, the hotel head of security finally figures out a thing or two. An opera singer in residence, who has played little role throughout, gets a delightful surprise. Delightful Jenny gets her just reward.
More deaths occur. Someone is arrested for murder. But is it the right someone?
