Murder Served Cold - Eric Brown - Bog

Shortly after Lord Elsmere re-insures his favourite painting for a hefty price, it is stolen and with no sign of a break-in. Elsmere is known to be struggling financially, so is it a staged theft or has one of his guests taken it? Seething animosities, jealousy, secrets and deception are all found once PIs Langham and Ralph Ryland take on the case.
