I have read a few novels by Winifred Peck, so I was intrigued to learn she had also written some mysteries.
Betty Morrison is the newly married wife of an Edinburgh lawyer, John. She accompanies her husband on a call to the Warrielaws, an old family whose members are constantly feuding. The most recent dispute concerns the fairy jewel, a chunk of amber said to be given to an ancestor by a fairy and subsequently encrusted in jewels. Jessica Warrielaw, the old lady who was left the estate, hadn’t spent a penny on its upkeep but instead has been selling off treasures and giving the money to her nephew Noel. Shis is planning on selling the fairy jewel.
Jessica’s sister Mary as well as the other potential legatees are horrified by this. Mary, who lives with Jessica in shabby rooms divided in half by physical markers, wants the jewel to stay in the family as does niece Cora. Niece Rhoda, on the other hand, would like money to start over in America. She is horribly managing and makes the life of weaker Aunt Mary miserable. Other potential heirs are Neil, of course, and Rhoda’s much younger sister Alison.
First, there is an odd incident at the house that seems like a break-in except nothing is missing. Then Jessica leaves for London, presumably to sell the jewel—and isn’t heard from again. John, as trustee of the estate, finally hires Bob Stuart, an ex-police detective and friend, to find Jessica.
Weeks later Jessica is found dead, not in London but in the estate’s dilapidated stables. The jewel is nowhere to be found. Was Jessica murdered? How did she get back home when Betty herself saw her on the train to London?
As is often the case with mystery novels of the period (1933), this novel is more concerned with the puzzle than characterization. However, several characters do have strong personalities. The plot is rather slow moving, and once or twice just when things were getting exciting, Peck drove me crazy by inserting a several-page description. However, I liked Betty and though the novel was entertaining.

Sounds entertaining, although those lengthy descriptions would drive me mad too. I might give this a try though…
