This has been out for months in the UK but only just got released here The fourth book in the series has Peter and Leslie learning new magic and working on several cases that seem to be leading all to the Faceless Man. A building project by a unknown magic practitioner becomes the focal point of the investigation. The housing project has more people that usual that rise out of it as stars in various fields including criminal. Something about the building makes several of the residents better in various ways.
