The Bishop's Secret by Fergus Hume

When Mr Cargrim took an idea into his head it was not easy to get it out again, and to this resolute obstinacy he owed no small part of his success. He was like the famous drop of water and would wear away any human stone, however hard it might be. Again and again, when baffled, he returned with gentle persistence to the object he had in view, and however strong of will his adversary happened to be, that will was bound, in the long run, to yield to the incessant attacks of the chaplain. At the present moment he desired to have an interview with Mrs Mosk, and he was determined to obtain one in spite of Bell's refusal. However, he had no time to waste on the persuasive method, as he wished to see the invalid before the bishop returned. To achieve this end he enlisted the services of Mrs Pansey.

That good lady sometimes indulged in a species of persecution she termed district-visiting, which usually consisted in her thrusting herself at untoward times into poor people's houses and asking them questions about their private affairs. When she had learned all she wished to know, and had given her advice in the tone of a command not to be disobeyed, she would retire, leaving the evidence of her trail behind her in the shape of a nauseous little tract with an abusive title. It was no use any poor creature refusing to see Mrs Pansey, for she forced herself into the most private chambers, and never would retire unless she thought fit to do so of her own will.
