Most Cunning Workmen (Arnold Landon Book 2)

Planning officer Arnold Landon found himself working in a difficult atmosphere when he took on the job of cataloguing the papers at Oakham Manor, a disputed inheritance which was up for sale and on which a US computer firm had already been granted an option. Not only did the principals of the computer firm descend on the Manor to make immediate plans for its use, but the rival claimant, another American, also put in an unwelcome appearance. Then Landon discovered a secret passage, a passage which led him not only to secrets within the Manor's walls, but to secrets within the company's boardroom, and to the identity of a murderer.
