<br/><br/> Psychic Nan Killian and Medium Sarah Lyon-White have been agents of Lord Alderscroft, the Elemental Fire Master, since leaving school. Now Lord Alderscroft assigns them to work with the famous man living at 221 Baker Street -- but not the one in flat B. They are to assist the man living in flat C. Dr. John Watson and his wife, Mary, themselves Elemental Masters of Water and Air, take the occult cases John's more famous friend disdains, and they will need every skill the girls and their birds can muster!
