Rosemary and Thyme: Up the Garden Path

SINOPSIS

An archaeologist posing as Rosemary dies mysteriously during a dig for Anglo-Saxon artefacts in the grounds of Lord Engleton's stately home, presenting the duo with a fresh mystery to solve. The gardens are unaccountably blighted by yellowing, forcing the estate to close its gates to the public, and a second death suggests somebody will go to any lengths for a piece of British history. Guest starring Julian Wadham.
