Bleeding in the Eye of a Brainstorm

Mama Spit just hasn't been herself lately. There used to be a time when she'd spew saliva at anyone who passed by her - even those who actually gave her money. And if her mouth was particularly dry that day, she'd at least acknowledge your presence by cursing from underneath her filthy blankets. Everyone knew that she was certifiably mad - including Dr. Robert Frederickson, more commonly known to the world as Mongo the Magnificent. Which is why the private investigator is so bewildered when Margaret Dutton - the former Mama Spit - appears before the Frederickson & Frederickson, Investigations offices one morning. She has no saliva to spew and no vulgarities to roar. She has come to thank him for his kindness and offer her help in his office. Abnormal behavior, indeed, from a madwoman. But Margaret has been transformed by a large black-and-yellow pill a stranger gave her just before he was brutally murdered. To Mongo, these pills are just another cheap street drug and the man another pusher - but to Margaret, these pills are her savior.
Thus begins George C. Chesbro's newest Mongo mystery. And things only get more complicated from here.
