Rowland once again delivers a mystery laden with details of period and place, with strong portrayals of palace intrigue in 17th-century Japan. Sano Ichiro has risen to the rank of Most Honorable Investigator for the shogun in 1690 Japan. As his fourth adventure (after 1997's The Way of the Traitor) begins, he is marrying the beautiful Lady Ueda Reiko. The wedding is interrupted by the sudden death of Hamune, one of the shogun's concubines, the victim of poisoned ink that Hamune used to give herself an intimate tattoo.
