Henry hated Wanda, his former wife, for divorcing him and marrying John a short time thereafter. About a month after Wanda married John, Henry secretly entered Wanda and John's rented apartment during their absence by using a master key. Henry placed a microphone behind the nightstand in the bedroom of the apartment, drilled a hole in the nearby wall, and poked the wires from the microphone through the hole into the space in the wall, with the result that the microphone appeared to be connected to wires going into the adjoining apartment. Actually the microphone was not connected to anything. Henry anticipated that Wanda would discover the microphone in a few days and would be upset by the thought that someone had been listening to her conversations with John in their bedroom. Shortly thereafter, John noticed the wires behind the nightstand and discovered the hidden microphone. He then called Wanda and showed her the microphone and wires. Wanda fainted and, in falling, struck her head on the nightstand and suffered a mild concussion. The next day John telephoned Henry and accused him of planting the microphone. Henry laughingly admitted it. Because of his concern about Wanda and his anger at Henry, John is emotionally upset and unable to go to work. If Wanda asserts a claim against Henry based on infliction of mental distress, the fact that John was the person who showed her the microphone will
