Interior designer Zan Moreland is on the threshold of a brilliant career in Manhattan, despite the sadness of the past two years following the kidnapping of her three-year-old son Matthew in Central Park. As Matthew's fifth birthday approaches, she is poised to embark on a brilliant new assignment; she is competing, however, with Bartley Longe, her former boss, whose hatred of her has been a constant thorn in her side.

So when suddenly strange events begin to unfold, with numerous credit card purchases she did not make and the apparent ordering of materials for a job she hasn't yet obtained, she starts to panic. To climax these events, photos are published that show what appears to be Zan Moreland herself kidnapping her son. The photos, captured by a tourist during that day and discovered later, seem to thoroughly discredit and implicate Zan.

Even her friends and supporters begin to doubt Zan, suggesting that she might be suffering from some kind of mental illness.

Meanwhile, miles away in a small farmhouse in Middletown, a secretive and reclusive young woman is holding a young boy in a closet.

What do a priest in Manhattan, a competitive designer, a young aspiring actress, and persons unknown have to do with the chain of events? And how will those in Zan's corner manage to convince the detectives that someone is actually impersonating Zan? Who is behind the nefarious plots and how has this person managed to pull it off?

I loved how the author gave us little tidbits of information, and showed how various characters had pieces of clues that would eventually lead us down the correct pathways. Impatiently I turned pages, guessing who might be behind it all, reluctantly turning away from the obvious choice, until finally, just before the end, I figured it out.

If you enjoy fast-paced mysteries with colorful characters, you will love "I'll Walk Alone: A Novel." The satisfying conclusion was definitely well-deserved. Four stars for the slight predictability in the plot.
