NEW YORK TIMES BESTSELLER • Diana Gabaldon weaves a dazzling tale of history, intrigue, and suspense in this first novel featuring one of her most popular characters from the Outlander saga: Lord John Grey.

The year is 1757. On a clear morning in mid-June, Lord John Grey emerges from London's Beefsteak Club, his mind in turmoil. A nobleman and a high-ranking officer in His Majesty's army, Grey has just witnessed something shocking. But his efforts to avoid a scandal that might destroy his family are interrupted by something still more urgent: The Crown appoints him to investigate the brutal murder of a comrade-in-arms who may have been a traitor. Obliged to pursue two inquiries at once, Major Grey finds himself ensnared in a web of treachery and betrayal that touches every stratum of English society—and threatens all he holds dear.
Praise for Lord John and the Private Matter
"[A] thoroughly entertaining and wonderfully witty historical mystery set in the richly detailed, occasionally bawdy world of Georgian England."—Booklist

"Packed with vivid description and detail. Gabaldon aptly transports readers to eighteenth-century London, with all its reeking humanity and glitteringly elegant excess."—BookPage
