Murder Is Easy is a detective novel by Agatha Christie, first published in the UK by the Collins Crime Club on 5 June 1939, and in the US by Dodd, Mead and Company in September of the same year under the title of Easy to Kill. Christie's recurring character, Superintendent Battle, has a cameo appearance at the end, but plays no part in either the solution of the mystery or the apprehension of the criminal.
