Detective Inspector Sidney Ressler and Edmund Reid in “Unfinished Business”

Reid, I cannot help but think the man's further excesses, his need to move beyond that initial batch... Dozens have perished, your wife almost among them... Had I not bowed to pressure to keep those bodies secret, the public knowledge of those deaths might have been enough to sate his madness.

Word of advice, Ressler. This work we perform, it does not serve to look backward. This city, wickedness will ever leave its spores here. You and I, we are not magicians. We cannot see through walls or into men's minds. Dozens perished, but hundreds who were ill are now well once more. We fight. We fight with all the skills we may muster. Beyond that, we may do no more.
