Tales From Dickens: BLEAK HOUSE by Charles Dickens

When the last bit of proof was fast in his possession Mr. Tulkinghorn, pluming himself on the cleverness with which he had wormed his way into Lady Dedlock's secret, went to her at her London home and informed her of all he had discovered, delighting in the fear and dread which she could not help showing. She knew now that this cruel man would always hold his knowledge over her head, torturing her with the threat of making it known to her husband.

Some hours after he had gone home, she followed him there to beg him not to tell her husband what he had discovered. But all was dark in the lawyer's house. She rang the private bell twice, but there was no answer, and she returned in despair.
