Rehab finds the bloodless corpse of a child on his ghetto doorstep, the victim of a ritual murder. The Tsyonim, barely tolerated at the best of times, are now the subject of suspicion and hatred in Arcassanne. And the captain of the city guard is determined to ensure that it is a ghetto dweller who is found responsible for murder. As his people prepare to flee once more from persecution, Rehab is determined to find the real killer - to prove his own innocence, and to atone for letting go of his brother's hand as they fled their birthplace in the last pogrom. Salvation lies unexpectedly close at hand, but is more terrifying, and more spectacular, than rehab could ever have imagined.
