The Open Road-published Lord Peter Wimsey Mysteries omnibus contains (big surprise) the first three titles in the Lord Peter/Harriet Vane series by Dorothy L. Sayers: Whose Body?, Clouds of Witness, and Unnatural Death. It has has dropped to $2.99 at Kindle US and Kobo US (couponable). I think some versions of some of these are PD in some countries, but in any case, $2.99 is a pretty good price for three classic titles, IMO.

A special edition of the first three classic mysteries featuring British aristocrat and sleuth Lord Peter Wimsey.

A gentleman needs hobbies. For Lord Peter Wimsey—a Great War veteran with a touch of shell shock—collecting rare books, sampling fine wines, and catching criminals help pass the time.

In Whose Body?, a dead man wearing nothing but a pince-nez is found in the bathtub of an architect’s London flat—and Wimsey encounters a bizarre puzzle.

Clouds of Witness brings Lord Wimsey to the family’s shooting lodge in Yorkshire. Humans are not meant to be targets, but Wimsey’s sister’s fiancé has been felled by a bullet—and his brother accused of the crime. The investigation will bring him into contact with a socialist agitator, a hot-tempered farmer, and a host of unseemly secrets.

In Unnatural Death, everyone expected the ailing and elderly Miss Agatha Dawson to die—just not quite so soon. When the doctor who treated her shares his suspicions with Wimsey, he sets out to discover who rushed the patient to her demise.

This exciting volume of renowned author Dorothy L. Sayers’s beloved cozy British mystery series is a perfect introduction for new readers, as well as a familiar friend for longtime fans.

Striding Folly is a collection of three shorter Lord Peter/Harriet Vane stories. It has also dropped to $2.99 at both Kindle US and Kobo US (again couponable).

In his final 3 stories, Lord Peter confronts the greatest mystery of all—fatherhood

For decades, Lord Peter Wimsey has made life tough for England’s criminal class. In town and country he solved some of the most baffling mysteries of the Jazz Age, facing down killers armed only with wit, charm, and a keen nose for deception. His work brought him 1 great reward: the love of beautiful mystery novelist Harriet Vane. After years of pleading, he has finally convinced her to marry him. Now the real adventure begins.

In the final 3 Wimsey stories, Lord Peter confronts land barons, killers, and the terror that comes from raising 3 young sons. Through it all, his clear thinking never fails him, and he solves these last puzzles as successfully as he did his 1st. He may be a family man now, but like good wine, a great detective only gets better with age.

Striding Folly is the 15th book in the Lord Peter Wimsey Mysteries, but you may enjoy the series by reading the books in any order.

This ebook features an illustrated biography of Dorothy L. Sayers including rare images from the Marion E. Wade Center at Wheaton College.

And finally, since we are talking about Dorothy Sayers books, I'll note that A Treasury of Sayers Stories, which is exactly what it sounds like, a collection of 24 short stories (mostly Lord Peter, a few Montague Egg, fewer others), is a long-term $2.99 title at Kindle US.
