Seven Amethysts by the Riverside

At a sunny picnic above Maidstone, Mrs. Letitia Harlow wears an amethyst brooch of seven matched stones, pinned to her shawl where the whole riverside party can see it.

The wind carries the shawl off, and once the cloth is chased down and returned, the brooch is gone.

An hour of searching the riverbank turns up nothing but a frog.

Lady Verity Crowe and her husband, Lord Alexander, are left with an untorn shawl, grass that held nothing, and a little silver catch that has been snapped.

In this witty Regency romantic mystery, a clever lady detective must learn where seven amethysts went in broad daylight, between a runaway shawl and a forfeit game.
