Lord Calne's Christmas Ruby

Fashionable London holds nothing for wealthy merchant's niece, Lalamani Finchurch. Except perhaps for an earl with a twisted hand and a charming smile. Why, for all the fortune hunters she has fended off since returning from India, is the one man who seems to likeable so against marrying for money?
Philip has inherited an earldom that his only two choices are to marry for money or to abandon Society altogether and return to his work as an engineer. Which is no choice at all, until a tiny woman with beautiful eyes and a fine mind dances with him on his last night in London.
When they meet again in a small country village, they join forces to uncover larceny and deceit, to rescue Lalamani's aunt from poverty, and to discover that pride is a poor reason to refuse a love for a lifetime.
