I should point out that I read an older edition of these stories, simply called "Carnacki the Ghost Finder". It's got all the same stories in it though, so I'm not sure what's been edited in this edition. Anyway, the previous reviewer compared Carnacki to both Holmes and Algernon Blackwood's John Silence, which is a fair comparison. While it's true that Holmes has rather more characterisation, I cannot agree with that reviewer over John Silence. The Carnacki stories are far more entertaining and well-written. In contrast, the John Silence stories are rather po-faced, with no characterisation at all, unless Blackwood's almost homoerotic descriptions of Silence's powerful, wise eyes, unusually calm demeanour and ability to radiate confidence count. I also prefer the Carnacki retold first person narrative style, which means his character comes across more through his phrasing. He's clearly an excitable individual, repeatedly leaning forward to ask his enthralled audience "Can you imagine it? Can you?"
I'm not really into "weird" stories, so I found the ghostless stories worked better than the others, but then detective stories are fraught with problems when the "baddie" doesn't follow natural rules which can be systematically followed. My eyes did glaze over with descriptions of pentacles and the accompanying paraphernalia, but you get exactly the same sort of thing with John Silence (maybe I should review those next). Altogether good fun for dark nights. Can you imagine it? Can you?
