The Visitor : a twisty, suspenseful page-turner

'Tis the season ... for a visit from a mysterious stranger . . . Izzie Mallon planned to spend Christmas alone - she hadn't counted on a visitor. But is he who he says he is? Izzie Mallon is looking forward to celebrating Christmas on a relaxing yoga retreat. At least, that is what she's telling her mother and colleagues. In reality, she will be shutting herself away from the festive season, and the snowstorm that has brought the city to a standstill, in her apartment on Henrietta Square -- the beautiful home she shared with her beloved husband Sam until his tragic death a few months ago -- with only her grief for company. Then, there's a knock at the door -- a stranger, stranded by the bad weather. He tells Izzie that he's Eli Sanders, her husband's long-time friend. Izzie has never met him in person, but feels she owes it to Sam to welcome Eli into her home. Even though her instincts say that she should do otherwise... As Izzie tries to reminisce with Eli about her husband, cracks in his story begin to show. But will she be able to see clearly through her grief before it's too late?
