Synopsis: “Lester Dunn led a rather drab, unremarkable life as the owner of a not very prosperous pharmacy in a not very prosperous pharmacy in a not very affluent London neighborhood. Grant Livesey lived a life of quiet luxury well-appointed house in the country. Yet, Lester Dunn and Grant Lievesy appeared to be the same person. Could the brain operation performed on Dunn have changed him into Livesey? Could one of his existences be merely a dream? Or could it be a frightening premonition of a disaster he was fated to bring upon himself?” — quoted from the inside front cover flap.
