In the middle of a heat wave, Jane and Maura find a man who died suspiciously in a bathtub full of ice. In trying to stay cool, Angela discovers a spicy tea that seems to be working, but it has unexpected romantic consequences.
When tenants complain of water leaks, a landlord finds the body of a man half-submerged in a bathtub. Initially, it is believed Richard Nelson did so to escape the sweltering heat outside. During autopsy, Maura discovers Nelson died of strangulation. His financials reveal him to be a millionaire. Although Nelson told everyone that he found the money while jogging, the investigation shows him to have been involved in a kidnapping. His accomplice killed him, thinking he kept the ransom for himself. Meanwhile, Angela drinks some tea to stay cool, but it has amorous side effects; and Korsak intends to find the owner of a lost dog, even though he names it and gets used to it.
