This reissue of a classic mystery originally published in 1939 sparkles with wonderfully wry humour and the energy of the time. John Rutherford finds himself puzzling the mysterious disappearance of a man from an evening of carol singing. The novel begins with: “A rather curious thing happened during the evening of Sunday, the 21st of December”. John narrates, and within a few paragraphs had me chuckling in appreciation. As John investigates it becomes clear that the darkest of deeds may have been committed, and he reports the case to Inspector Charlton. Clifford Witting wrote 16 novels between 1937 and 1964, Catt Out of the Bag is the fourth involving Inspector Harry Charlton, yet you can quite happily read this as a standalone. I found myself completely wrapped up in the era, and thoroughly enjoyed the lively wit. Sitting as it does within the ‘Golden Age’ of mystery writing Catt Out of the Bag really is a perfect Christmas Mystery.
