Sweet Danger: Albert Campion #5

After centuries as a Balkan backwater, the sleepy town of Averna has overnight become a stunningly valuable port, thanks to an earthquake that rejiggered the regional topography. But to whose coffers will that value accrue? Albert Campion has a hunch that the answer is to be found in a tiny Suffolk village, where a peculiar and dead broke family may be able to lay claim to the Averna fortune, provided they can produce the requisite proof of lineage. The proof? Nothing terribly difficult: Just your average ancient riddle, stolen drum, long-lost bell, priceless crown, and, oh yes, a necklace of disappearing rubies.
