Resumen

Put on by Cunning is a novel by British crime-writer Ruth Rendell. It was first published in 1981, and features her popular series protagonist Inspector Wexford. It is the 11th in the series.
The title comes from a quotation from Shakespeare's Hamlet, Act V Scene II:
"How these things came about: so shall you hear Of carnal, bloody, and unnatural acts, Of accidental judgments, casual slaughters; of deaths put on by cunning and forced cause, And, in this upshot, purposes mistook Fall'n on the inventors' heads: all this can I Truly deliver".
In the US, the novel was published under the title Death Notes.
