The Twisted Blackmailer – Watson and Holmes Book 1 by Tammy Garrison
Nothing’s ever easy when Sherlock Holmes is involved. Joanna Watson needs sports and academic scholarships if she is going to make it all the way to med school. That means keeping out of trouble, and her school record squeaky clean. But upon befriending the mysterious New Girl, Joanna has her perfect record ruined, skips school for the first time in her life, and finds a blackmailer aiming a gun in her direction. All she knows is that she’s going to get grounded… if they get out of this alive.
