This book took me months to "get into." I'd read a few pages, lose interest, pick it back up, put it back down. But once I decided to read enough to give the book a chance, I became very drawn into the fascinating history of poisons. I thought the author's actual story of her grandfather who'd allegedly poisoned two of his children slowed the book down in spots, though by the end I was as "hooked" to that mystery as to the tidbits about other accused "poison users" and their victims and methods! Wonderful.
