A Cat on the Bus

A Cat on the Bus by Lydia Adamson (Contains Affiliate Link)

     Alice Nestleton, once mockingly referred to as the Cat Woman by the local law enforcement, is finally getting everything she wants: a juicy role in a slick new TV series, a debonair leading man on camera and off, and enough money to give up cat-sitting for good.  But when a simple crosstown bus ride turns Alice into a the witness of a senseless multiple homicide- perpetrated by a bizarre killer who leaves her cat behind- the NYPD begs the Cat Woman to return as a consultant in the case, and Alice must make room in her perfect life to play investigator one last time.
