When barista Martha "Marty" Hudson suddenly inherits a Victorian home at 221 Baker Street in the heart of San Francisco, she's ecstatic. But between a dead body, the hot ME, Dr. John Watson, and the grumpy SFPD Detective Lestrade, Marty's luck takes a turn for the worse. Luckily her best friend, Irene Adler, has a solution—invent a fake PI, Sherlock Holmes, and investigate the murder themselves!
