This episode was conceived as a bit of a 'bottle show' but turned out to be one of the best-remembered episodes of the entire McMillan and Wife series.
It does have flaws - the regular cutaways to Sergeant Enright's romantic weekend, although intended to create suspense (will he turn up in time to save the Commissioner and Sally?) are just annoying. And for a Police Commissioner, McMillan is remarkably foolish about security at times - such as not keeping the front door locked! Nevertheless, it's a fun episode with a slightly darker hue than normal, generating a fair measure of suspense as the 'Asylum Killer' unfolds a sinister and apparently foolproof plot to make the Commissioner and Sally his latest victims - right down to supplying the Death March as musical accompaniment.
