Here’s a tightened version, right around 150 words:
As the youngest of four sisters, Miss Eudora Mifford has always lagged behind. While her siblings find husbands and solve murders, she leads a perfectly respectable—yet dreadfully unremarkable—existence.
So when she literally stumbles over a corpse, Eudora seizes her chance to shine. Unfortunately, no one else believes she’s up to the task.
When a cantankerous viscount is killed at a snowbound house party, Eudora vows to prove herself by solving not one but two murders. The only person willing to indulge her sleuthing is Lord Robert Delaney, Baron Bloomsbury—a man far more interested in courting her than chasing clues.
Determined to win her hand, Robert joins her investigation. With a brooding heir, a scandalous wife, and an old Oxford rival among the suspects, there’s no shortage of motives.
But can Robert help Eudora catch a killer—and finally persuade her that the greatest clue of all is his love?
