The Teller Trilogy

Remmel Kell was named the CEO of Account Force USA, the largest franchise of banks in the United States. To the public he seemed to be a charismatic and highly educated entrepreneur. When he gave a speech or did an interview everyone stopped to listen. Yet those close to him knew Remmel had a very morbid obsession. He would target single mothers with two children. Then brutally murder them one by one in the order of ascending age. It was the perfect ratio and order, until, of course, he messed it up.
