The Round Dozen — Elizabeth Cadell

At the helm of the family's sprawling import business, London bachelor William Helder unexpectedly finds himself next in line to track down a priceless family heirloom. Missing since 1702, a last antique silver flagon is needed to round out a set of twelve.

Spurred on by his stepmother, William soon takes his sleuthing seriously when clues lead to the intriguingly beautiful Hazel Paget. Hazel, at first engaged to another, helps William succeed in his quest and finds her heart won in the bargain.
