The story is historically grounded but lacks tension due to the known identity of the poisoner, resulting in a lengthy, somewhat dull investigation.
The reviewer finds the novel historically interesting but feels the narrative suffers because the poisoner's identity is revealed early, removing the element of mystery and suspense. This makes the investigative plot feel slow and drawn out, diminishing the overall excitement. They suggest the story might have been more effective if it had been more concise or if the author had introduced more mystery to engage readers more deeply.
