Discovered in the ruins of a Castle in the early 1900s, The Lost MacGreagor Books are sequels to the Marblestone Mansion Scandalous Duchess Series.

Charles MacGreagor was hired to rebuild Glenartair Castle after it burned four years earlier. His men were hard working, supplies were coming in on time finally, and he was well satisfied with the progress. He was satisfied, that is, until the floor of the old castle gave up another of its secrets.
