The Spell of the Black Dagger loe-6

The means of making a wizard’s magical dagger was a closely-guarded secret, but Tabaea the Thief had spied on the lessons a wizard gave his apprentice, and thought she could do it herself. She was wrong. What she made was not a wizard’s athame, but something new -— and very, very dangerous. With the Black Dagger’s magic Tabaea thought she could have everything she had ever wanted. If people who got in her way died, that did not greatly trouble her. It was up to Lady Sarai, daughter of the Minister of Justice, to ensure that Tabaea’s mad plans did not bring down the entire Hegemony of Ethshar.
