John Marcone hires Goodman Grey for a cleaning job: a rival concern which Marcone cannot confront directly has opened a brothel offering preteens to clients interested in raping children. This breaks Marcone's only unbreakable rule - do not harm children. Grey's secretary/driver/hitwoman Viti does not like Marcone, but he accepts payment of a dollar, toward Rent.
The job is simple and swift: Grey and Viti dispose of the brothel's security guards and rescue the six children already there, which they plan to entrust to Harry Dresden for help. Grey reports to Marcone the operation's complete success. He also sends him the pictures of six clients, advising Marcone to have a better grip on the latters' liabilities.
