A Fatal Fondness - Mary MacDougall Mysteries, #4

It's 1902 and Mary MacDougall's new cases hardly portend any danger or significance. There's the affair of the nicked napkin rings.the problem of the purloined pocket watch...and the matter of the four filched felines. What the heiress/sleuth doesn't know is that one of these modest little matters will blow up into the most consequential and perilous case of her budding career. What begins in triviality mushrooms into disappearance, betrayal, international intrigue, and murder.
As she learns more and more, Mary's prospects for making the acquaintance of an assassin's blade improve dramatically. Witty, fast-paced, and enthralling, A Fatal Fondness-the fourth tale in the series-delves deeply into Mary's world and paints the portrait of an unconventional young woman ever-ready to defy propriety for the sake of justice.
