The Sin Within Her Smile

Description for THE SIN WITHIN HER SMILE by Jonathan Gash:

This time, Lovejoy's on the auction block

When Lovejoy himself is put on the block among marmalades and lawnmowers at a charity auction -- and billed as "Slave for a Day" -- he's bought for an outrageous sum by a rich and luscious mystery lady. Soon he is drawn into a fraud involving early Celtic gold in Suffolk -- but the joke becomes deadly when an overinquisitive friend is murdered. And what begins as an adventure through the world of art and antiques turns out to be a wild and fatal journey.

This is #17 in A Lovejoy Mystery.
