Davis Breen had a dilemma on his hands.For the past week and a half, he had been searching for his ex-lover and partner, Dr. Suzan Dwyer.She had left some of her personal items behind when she moved out, and he wanted to know if he should box them up and send them over to her, or if he should simply donate the items-a pair of ski boots, several cable-knit sweaters, a couple of handbags and some costume jewelry-to a thrift shop.Davis tried her cell phone several times but received only a faint buzz, similar to the sound of a flat line on a heartbeat monitor, her voice mail no longer available.Had she disconnected her phone service?
