I was persuaded to buy this book by the attractive cover design (yes, I know!) and the promise that this might be a series worth getting my teeth into. In the end I felt it was something of a letdown. The 1930s setting is well-established, and the deliberately two-dimensional characters are pleasant enough, but the STORY IS ABSOLUTELY USELESS. It's a classic country-house murder setup, with plenty of opportunity for depth and intrigue, but very little of either resulted. There is barely a moment of tension in the whole book, and by the end of all the pointless to-ing and fro-ing I couldn't have cared less who did the murder. The lead characters (Verity and Edward) have some potential to be engaging in further stories, but the plotting of "Sweet Poison" has just put me off any more of these novels completely. And what a dreadful idea to make them such carbon copies of Lord Peter Wimsey and Harriet Vane! This just amplifies the considerable inadequacies of these two cardboard creations and does nothing more than make you long to be reading the original. Also, the prose veers into PG Wodehouse territory on quite a few occasions which just muddles the style further - "comedy dramas" rarely work on TV, let alone in print. Go and read Sayers' "Habeas Corpus" instead - you'll have more fun!
