Grant Allen,
An African Millionaire
(1897)
“ What could have seemed more transparent than Medhurst, the detective, till he ran away with our notes in the very moment of triumph? What more innocent than White Heather and the little curate, till they landed us with a couple of Amelia's own gems as a splendid bargain? I will not take it for granted any man is not Colonel Clay, merely because I don't happen to spot the particular scheme he is trying to work against me. The rogue has so many schemes, and some of them so well concealed, that up to the moment of the actual explosion you fail to detect the presence of moral dynamite. ”
