Mollie Mack, Private Detective

Mollie is excited! She has been a private detective for six months, and FINALLY a BIG case has landed on her desk. If she solves it, it will make the papers and make her agency famous. She needs to give it her full attention; BUT, she already has three cases she is working on. And when she gets an unexpected lead for her oldest case, she HAS to run with it. Could her new BIG case be linked to her oldest case?
