Death at Apothecaries' Hall Book

John Rawlings stood in the shop at Apothecaries' Hall discussing the extraordinary outbreak of food poisoning that struck the liverymen who attended dinner at the Worshipful Society the previous day. And how Liveryman Alleyn might have died had John not given him a herbal remedy. Except that the following day Liveryman Alleyn did die. Rawlings is asked to investigate whether it was deliberate poisoning. But who would want to poison the apothecaries? As Rawlings searches for gossip, he discovers that a fellow apothecary visited the dying man's house on the morning of his death, and that a bereaved parent has vowed vengeance on the entire Society.
