The wedding is over and the newly-married Mainwarings are enjoying their Caribbean honeymoon, blissfully unaware of a discovery at Hollin Hall that will embroil them in a tragedy that occurred thirty-seven years earlier. As 1968 draws to a close, Patsy and Jason Mainwaring are adjusting to married life. After the stress and strain of the previous six months they are anticipating spending some time quietly together at Hollin Hall. However, the discovery of a mysterious mirror and an unexpected visit by an old lady plunge them into a scandal that overturns all they thought they knew about Jason's distant relatives, Jack and Annie MacKenley. Patsy may have hoped that she was leaving ghosts behind her when she moved to Northumberland but a restless spirit from the past has a score to settle. 'Shadows' is the third book in the Abbey Grange saga.
