Infernal Triangle — Elizabeth Chater

When Wilfred first meets Lydia, she's in the midst of a face-bashing, hair-pulling brawl in a dirty alley in Italy. He breaks up the fight and, feeling sorry for her, gives her the business card of his valet, Wiggins.

Wiggins is then murdered.

The Assistant Commissioner reluctantly sends for Jamie Jarvis, though dubious of his so-called “special talents.” After forty-eight hours of not coming up with anything, Jamie Jarvis's paranormal abilities may be the only thing that can solve this heinous crime.

A short story.
