'Mrs. Jones' by B. A. Morton

The story of a New York cop and an English woman who witnesses a murder, Mrs. Jones is a gripping thriller and delightful love story rolled into one. Fast-paced and steaming with sexual tension, the plot has more twists and turns than a staircase in a Big Apple skyscraper and leaves you feeling just as breathless at the end. There's a surprise around every corner as maverick cop, Tommy Connell, tries to solve the mysteries of the murder, the missing money and the cute, little woman from England.
Occasionally, I worried about the lack of judgement shown by the impulsive Connell (especially, when he led the bad guys back to his family home.) But I was so gripped with the plot and the characters that I just had to see it through and find out why everyone - including Connell - were so desperate to get their hands on the delightful Mrs. Jones.
The novel left us brilliantly poised for a sequel - for which I can hardly wait.
