Dark Horse (2013) is a crime novel by Australian author Honey Brown.

On Christmas Day Sarah Barnard escapes her disapproving parents by taking her trusted but damaged black mare Tansy into the Tasmanian mountains.

Trapped by a sudden storm she takes shelter but slowly comes to realise that she is not alone.

Where is the rich, dark earth, brown and moist?

-John Marsden, The Rabbits Karen Chisholm in The Newtown Review of Books cited the novel's suspense as a major attraction: "There are a few authors out there who write books that just about guarantee that sleep will be lost, and lights will be left on for quite some time after finishing them, and as with Brown’s previous work, Dark Horse has this effect.
