Hallowe'en Party: Starring John Moffatt (BBC Radio Collection)

Reviewers found "Hallowe'en Party" to be an enjoyable read for fans of Agatha Christie, particularly those who appreciate the partnership between Hercule Poirot and Ariadne Oliver. Many highlighted the book's success in creating an atmospheric, "Halloweenie" or autumnal setting that provided a sinister backdrop without being genuinely frightening. The novel is praised for its classic "whodunit" formula, engaging writing, and Christie's characteristic wit, which some found present even in her later works. Readers enjoyed the twists and turns of the investigation and the fascinating insight into Poirot's deductive methods, with some describing the tale as engrossing and the characters, at times, as complex.

However, many critics noted that "Hallowe'en Party" is not considered one of Christie's strongest novels. Recurring complaints included a slow opening with an abundance of seemingly irrelevant details, and a plot that some found meandering or overly complex, featuring too many characters. Reviewers often felt the dialogue was repetitive and that many characters lacked distinct voices. A significant number of readers found the mystery predictable, claiming they could identify the culprit early on, and expressed disappointment with an ending that felt either unsatisfying or lacked the usual surprising impact. Furthermore, several reviewers pointed out a minimal connection to the Halloween theme beyond the initial party setting, and some felt the author was not at her prime, leading to less gripping characterizations and a less suspenseful narrative.

Overall, "Hallowe'en Party" garners a mixed reception, often being described as a worthwhile and entertaining read despite its perceived flaws. It is generally recommended for established fans of Agatha Christie and particularly those who enjoy the character of Hercule Poirot and his interactions with Ariadne Oliver. Readers looking for a light, quick mystery with an an autumnal ambiance, rather than a truly terrifying or deeply suspenseful tale, would likely find this book appealing. However, those new to Christie's work or preferring her more acclaimed, tightly-plotted earlier novels might find this particular entry less representative of her best craft.
