Barnaby Grimes is attacked one night by a dog. He kills it - but that's not the end of this particular mystery - as Barnaby finds himself swept up in a world of crooked doctors, poor and ill-advised patients, strange tonics and expensive furs. Could there be more to the seemingly respectable Dr Cadwallader and the tonics he doles out to the poor?
