An Outside Chance by Emily E K Murdoch

George Chance, Earl of Lindow, is going to be rich. Probably. As soon as these cards behave.
And he most certainly doesn’t need a woman—a woman!—beating him at cards and then disappearing into Bath Society.
After all, he’s got his horses to concentrate on. And they really win start to win races. Soon.

But every time he attempts to concentrate, the irritating and beautiful woman keeps appearing and beating everyone who challenges her at cards. An outside chance, every time.
To Miss Doris Loughty—“Dodo” to her loved ones—it is not an outside chance. It’s mathematics. Probability, calculations that are so simple to her and yet seemingly impossible to others.

But the winning itself isn’t important—it’s the money she so desperately needs that is the priority. So when the arrogant Lord Lindow demands that she teach him all her tricks and promises to pay for the pleasure…
Well. There’s no chance anything can go wrong, can there?
