The Red-Headed Man by Fergus Hume — Read

Here, then, was a new complication, and one entirely unforeseen. The dead man, false to his reputed character for uprightness and loyalty to his wife, had been in love with Lydia Hargone, and she, according to Donna Inez, while pretending an affection for Blake, was devoted to Frederick Leighbourne. Torry was so perplexed over the matter that he determined to adopt a frank and open policy, and visit Lydia and Leighbourne in turn. From one or the other he hoped to get at the truth of the accusations directed against them by Mrs. Grent.

With this idea the detective drove to Fleet-street the next morning and sent in his card to Frederick Leighbourne, with a request for an immediate interview. The young banker was annoyed by the visit, and very unskilfully shewed his annoyance when Torry was admitted into his room. For this peevishness, however, the detective cared little, so long as he secured an interview, and he seated himself near Frederick with a smiling face.
