The third book about the detective team Siri and Max opens with a classic locked-room mystery about a stately mansion. A priceless art treasure is stolen and the culprit must be one of the guests in the great hall. Siri and Max take on the case, the most unpleasant they've dealt with yet.
Siri is as dynamic as ever. And Max thinks quickly. But will this be enough to save them when they're facing something entirely inexplicable –a ghost!
