Plot summary.
After regaining his confidence and will to live (lost in Paths of Darkness, when Drizzt Do'Urden seemed to have died without being defeated fairly by Artemis, thus apparently taking from him the ability to prove to himself that he was a better fighter), Artemis Entreri finds himself allied with the mercenary Jarlaxle as the drow's tie to the surface world. Caught in the plans of Jarlaxle's band, Bregan D'aerthe, Artemis finds himself back in Calimport, the city in which he became known as one of the greatest assassins in Faerûn. Without many ties to the city after spending his time in captivity to the drow, Entreri must once again make his name known while trying to survive against the guilds of Calimport and Jarlaxle's lieutenants, Berg'inyon Baenre, Raiguy Bondalek, and Kimmuriel Oblodra. At the same time Jarlaxle succumbs to the mental intrusions of the crystal shard, Crenshinibon, as it pushes Jarlaxle to fulfill his unending ambitions. This is also the third novel in the "Paths of Darkness" series.
