This is one of those detective novels I usually laugh at and deride - especially when it has a dumb-ass title like this one does. I flatly refuse to read any such book that has the word 'sleuth' anywhere in the blurb and this one didn't, but it may as well have for what it was. My mistake was in thinking that this might be different in that it was a pair of witches that were the amateur investigators. I was curious as to how this would work. Couldn't they just do some witchcraft to determine who the perp is?! The trick in writing a novel like this is that you have to put in some valid reason(s) why they couldn't do precisely that (which would have meant a very short and boring series!). The problem is that these authors failed to do so and simply left the question begging. That's a really poor way to treat your readers.
So what I got was the absurdity of two quite powerful witches doing the detecting job precisely like someone who isn't a witch would do it - apart from a sprinkle of pixie dust here and there (apparently pixie dust can detect traces of blood, but it also destroys those traces). So I have to wonder what is the point of making them witches in the first place? Having done that, it would have been the easiest thing in the world to have Witch One say, "I wish we could wave a wand and solve this" and have Witch Two retort, "Now Esmeralda, you know perfectly well that when a person kills another person, their true self is horribly warped by the violence done to their soul. Because of that, we can't see who it was, so we have to solve this the old fashioned way!" or words along those lines (and perhaps not quite so baldly!), but these two authors either were too clueless to see there was a major plot hole, or they simply didn't care. Either way, their readers deserve better.
To write about these characturds being very able witches and then have them pottering around without being able to lift a wand to solve the murder is just silly. The author has made the witches 250 years old, too, so there's that issue! Why she chose to do that I do not know, but the issue here is the same one that those asinine young adult vampire novels suffer. Someone who has been around for a quarter of a millennium isn't actually forty or fifty even if they look like they are. Such a person would not remotely behave like a person of that age (or be interested in a boring teenage slip of a girl unless he was into child pornography), yet these two authors write about the antique witches like they're really the age they appear to be. That's like saying a fifty-year-old would have the mentality of a ten year old. It doesn't work. Neither does the claim that witches age until twenty-five and then their ageing slows dramatically, which 'explains' how they continue to look young. Fine, if that's the way it is, but to say that's how it is and not even pretend you have a valid reason for that is just lazy writing. Why 25? Why does it slow? These authors don't give a shit.
Worse than this, we have these biddies in the story tampering with evidence. This happens all-too-often in this kind of story, going all the way back to Agatha Christie and Hercule Poirot. He frequently keeps the police from solving a crime by withholding evidence. He won't even share his suspicions - all because he's an arrogant little tool who thinks he's better than anyone, and evidently deems it more important that he gets the celebrity value of solving the crime than it is to bring the criminal to book with all haste and by any means necessary. In reality, such a 'sleuth' would be arrested for obstructing justice!
In this story, the first notable thing that happens after the body is discovered is that their pixie dust destroys the blood evidence, but before that, they failed to report a scrap of torn fabric they found which is from the victim's clothing. As soon as they found that scrap stuck in a door jamb, they immediately leapt to the conclusion that the dead woman had been murdered! The discovery of the blood came afterwards. These things are precisely why I have a problem with these 'amateur sleuthing' series. I'd thought adding witches to the brew might make it readable, but I was wrong. It actually made it worse! I quit this nonsensical story right after the destruction of evidence.
I don't object to amateur detectives, not in principal, but I do object to sloppy-writing where things are just taken for granted, evidence is destroyed or withheld, and the 'sleuths' simply don't care about collaborating. That's just simplistic, stupid and lazy, which is why I rarely even look at this kind of a series. I certainly cannot commend this one based on how poorly-written the opening chapters were.
