• Daily Express, of Cat Among the Pigeons: ‘Immensely enjoyable.’
• The New York Times: ‘To read Agatha Christie at her best is to experience the rarefied pleasure of watching a faultless technician at work, and she is in top form in Cat Among the Pigeons.’

33. The Adventure of the Christmas Pudding (1960)

‘This book of Christmas fare may be described as “The Chef ’s Selection.” I am the Chef!’ Agatha Christie writes in her Foreword, in which she also recalls the delightful Christmases of her youth at Abney Hall in the north of England. But while the author’s Christmases were uninterrupted by murder, her famous detective’s are not (see also Hercule Poirot’s Christmas). In the title novella, Poirot—who has been coerced into attending ‘an old-fashioned Christmas in the English countryside’—gets all the trimmings, certainly, but he also gets a woman’s corpse in the snow, a Kurdish knife spreading a crimson stain across her white fur wrap.

Collected within: The Adventure of the Christmas Pudding; ‘The Mystery of the Spanish Chest’; The Under Dog (novella); ‘Four-and-Twenty Blackbirds’; ‘The Dream’; and a Miss Marple mystery, ‘Greenshaw’s Folly.’

• Times Literary Supplement: ‘There is the irresistible simplicity and buoyancy of a Christmas treat about it all.’

34. The Clocks (1963)

Sheila Webb, typist-for-hire, has arrived at 19 Wilbraham Crescent in the seaside town of Crowdean to accept a new job. What she finds is a well-dressed corpse surrounded by five clocks. Mrs Pebmarsh, the blind owner of No. 19, denies all knowledge of ringing Sheila’s secretarial agency and asking for her by name—yet someone did. Nor does she own that many clocks. And neither woman seems to know the victim. Colin Lamb, a young intelligence specialist working a case of his own at the nearby naval yard, happens to be on the scene at the time of Sheila Webb’s ghastly discovery. Lamb knows of only one man who can properly investigate a crime as bizarre and baffling as what happened inside No. 19—his friend and mentor, Hercule Poirot.

• The New York Times: ‘Here is the grand-manner detective story in all its glory.’
• The Bookman: ‘Superlative Christie…extremely ingenious.’
• Saturday Review: ‘A sure-fire attention-gripper—naturally.’

35. Third Girl (1966)

Hercule Poirot is interrupted at breakfast by a young woman who wishes to consult with the great detective about a murder she ‘might have’ committed—but upon being introduced to Poirot, the girl flees. And disappears. She has shared a flat with two seemingly ordinary young women. As Hercule Poirot—with the aid of the crime novelist Mrs Ariadne Oliver—learns more about this mysterious ‘third girl,’ he hears rumours of revolvers, flick-knives, and bloodstains. Even if a murder might not have been committed, something is seriously wrong, and it will take all of Poirot’s wits and tenacity to establish whether the ‘third girl’ is guilty, innocent, or insane.

• Sunday Telegraph: ‘First-class Christie.’
• Financial Times: ‘Mesmerising ingenuity.’
