The Three Locks (A Sherlock Holmes Adventure Book 4)

Details: From the glow of London’s theatre district to the buzzing Cavendish Laboratory in Cambridge where physicists explore the edges of the new science of electricity, Holmes and Watson race between the two cities to solve the murders, encountering prevaricating prestidigitators, philandering physicists and murderous mentalists, all the while unlocking secrets which may be best left undisclosed.
