Unnatural Death by Dorothy L Sayers

"Our ancestors are very good kind of folks, but they are the last people I should choose to have a visiting acquaintance with. " Sheridan: The Rivals

That excellent prelate, Bishop Lambert of the Orinoco Mission, proved to be a practical and kind man. He did not personally know the Rev. Hallelujah Dawson, but thought he might belong to the Tabernacle Mission -- a Nonconformist body which was doing a very valuable work in those parts. He would himself communicate with the London Headquarters of this community and let Lord Peter know the result. Two hours later, Bishop Lambert's secretary had duly rung up the Tabernacle Mission and received the very satisfactory information that the Rev. Hallelujah Dawson was in England, and, indeed, available at their Mission House in Stepney. He was an elderly minister, living in very reduced circumstances -- in fact, the Bishop rather gathered that the story was a sad one.
