Quiet antiquarian Arnold Landon (A Gathering of Ghosts) is now on holiday from his Northumberland Planning Office job, cataloguing the library at medieval Oldham Manor--where there's an ownership dispute raging as the Manor. is being taken over by an American conglomerate. So Landon strikes up a tenuous friendship with aging conglomerate-head John Torrance, who's in the throes of putting together an international consortium based on new computer-chip material. And when Landon and Torrance together discover a secret tunnel from an abandoned kitchen, they find links to the power-games going on within the conglomerate (among Torrance's ambitious aides), as well as connections with the murder of engineer Keith Enright. But it's only after Torrance's near-fatal heart attack that Landon takes an openly active role--showing up at the final merger conference to throw a spanner (unconvincing) into the works. Lewis labors hard to evoke the Manor's medieval past, and he philosophizes mightily on the dehumanizing aspects of big business; but, less rewarding than A Gathering of Ghosts, this is a longwinded slog most of the way through.
