Found a pile of "new" Patricia Wentworth novels for sale for $2 each, so bought as many as I could.

Originally published in 1948. From the amazon.co.uk website:

"Synopsis
Mary Strokes was walking through Dead Man''s Copse when she saw the body of a young woman dressed in a black coat, black gloves, no hat and an eternity ring set with diamonds in her ear but when she took Detective Sergeant Frank Abbott to the wood, the body had vanished.

About the Author
Patricia Wentworth was born in India and after writing several romances turned her hand to crime. She wrote dozens of bestselling mysteries before her death in the late Sixties, and was recognised as one of the mistresses of classic crime."

RELEASE NOTES:

I am going to the bookshop later (they''re having a half-price sale) for ... yep, books, and intend to leave this one on one of the cars parked outside.

Released for the 2007 Never Judge A Book By Its Cover Release Challenge: Week 32 (Pink).
