Although he was watching closely when the mummer was poisoned it took Gil Cunningham several days & three more poisonings to work out how it was done. Danny Gibson & Nanty Bothwell rivals for the affections of Agnes Renfrew the apothecarys pretty daughter are also good friends. When they both take part in the festive play at the house of Gils sister Kate it ends in Dannys death apparently by poison from his friends flask. So was it deliberate & if not why wont Nanty defend himself? Why is Agnes eccentric brother Nicol so insistent that Nanty had the wrong flask & why do none of the apothecaries in Glasgow recognize the poison it held? Gil convinced Nanty is innocent sets out to answer these questions & finds himself enmeshed in the tensions of the Renfrew household & the tangled relationships among the apothecary houses. & then a second & third death confuse matters further still & bring Gils wife Alys into the investigation.
