"Blood is Thicker" is the eighth episode of season two of Elementary. It first aired on CBS on 14 November, 2013.


Sherlock and Joan investigate the murder of a young woman and tie her to a billionaire technology CEO. They are shocked to discover that the victim is the CEO's illegitimate daughter, and that the CEO is in poor health after receiving a heart transplant. Joan questions the CEO's wife, who reveals that the victim was donating blood to her father and was recently written into his will. Conversation with the victim's on-again-off-again boyfriend leads to the discovery that the victim was ill, and Joan realises that the actual target was the CEO, who dies during the investigation. Sherlock and Joan goad the wife into admitting that she was using the daughter as an incubator for the antibodies used to destroy the CEO's new heart and kill him. Meanwhile, Mycroft tries to convince Sherlock to return to London, saying that their father is disappointed he hasn't returned to his work at Scotland Yard. Mycroft's final private phone call shows that he is lying to Sherlock, though the cause and goal are not clear.
