A gruesome death caused by a deadly poison. A family friend accused of murder. Just days ago, Amelia Greystone was browsing the shelves of Mr. Tooley's apothecary shop. Now he stands accused of murder and Scotland Yard Inspector Henry Field is the only person Amelia trusts to untangle the truth. Henry is far from pleased to have Amelia involved in his latest case, but soon her father is as well. Unfortunately, the evidence against their friend is damning. Yet the deeper Henry digs into the accusations, the clearer it becomes that more than one person had reason to want the victim dead and the apothecary blamed for it. With each clue that emerges, Amelia and Henry must separate truth from deception before the wrong man is condemned. But one shocking twist strikes so close to home that it threatens both the investigation and their deepening bond. Can they unveil the killer before another innocent life is claimed by the apothecary's poison? Escape to the dark streets of Victorian London with the seventh novel in the bestselling Field & Greystone series-perfect for historical mystery readers and fans of Irina Shapiro, Cara Devlin, and Miss Scarlet and the Duke.
