Like Seven Dead, this actually includes a love story as well, although of a rather different stripe (and maybe a bit less of the focus, since neither party is seriously suspected of the murders). It’s less prominent than the love story in Seven Dead, and thankfully less creepy as well, with some rather good scenes between the two of them negotiating their relationship. At the same time, there’s a convoluted mystery going on with several deaths, complex interrelationships and, well, the usual stock in trade of Golden Age crime fiction, really. It’s a country house mystery, too, just to hit all those traditional notes.
I found it solidly entertaining, and though it’s a bit less weird/creepy than Seven Dead, I think it was probably stronger for it. There’s something about Farjeon’s writing that I find rather more-ish, and I’d gladly pick up a bunch more of his novels. Sadly, I only seem to have The Z Murders left… though I should check for something by other publishers or maybe as an ebook.
