Book Jacket: The Red Widow Murders

the red widow murders by John Dickson Carr

They say that a particular room in Lord Mantling’s mansion is haunted. Known as the Red Widow’s Chamber, the now-sealed quarters once housed the wife of a guillotine operator in the French Revolution. Since she died, the house has been the setting for a century of unsolved horrors, from the death of a man in 1802 to the death of a child in 1895, and a number of mysterious mortalities in the years in between. Now, in 1935, eight men and women join at the manor for a sinister experiment to determine the truth behind the haunting once and for all: they each draw a card, and whoever pulls the Ace of Spades must spend a night in that terrifying room. But the challenge turns fatal when the man selected for the task is found poisoned the next morning when the doors are opened. The locked room was guarded all night, so nobody could have entered or escaped; what’s more, the deadly toxin could only have entered through a break in the skin, but no wounds were discovered on the body. Is this evidence, at last, of a nefarious spirit at work, or of a diabolical and ingenious killer? Can Sir Henry Merrivale, called in to take note of the night’s proceedings, examine the clues and deduce the truth?

The offices of publisher and renowned stamp collector Donald Kirk are often host to strange activities, but the most recent ---the murder of an unknown caller, found dead in an empty waiting room--is unlike any that has come before.

Book Jacket: Miraculous Mysteries

miraculous mysteries

Impossible crime stories have been relished by puzzle-lovers ever since the invention of detective fiction. Fiendishly intricate cases were particularly well suited to the cerebral type of detective story that became so popular during the ‘golden age of murder’ between the two world wars. But the tradition goes back to the days of Edgar Allan Poe and Wilkie Collins, and impossible crime stories have been written by such luminaries as Arthur Conan Doyle, G.K. Chesterton, Dorothy L. Sayers and Margery Allingham. This anthology celebrates their work, alongside long-hidden gems by less familiar writers. Together these stories demonstrate the range and high accomplishment of the classic British impossible crime story over more than half a century.
