Hanging Hannah — Evan Marshall

With their very first mystery, Missing Marlene, widowed literary agent Jane Stuart and her tortoiseshell cat, Winky, left mystery fans purring for more. Now the well-read detective duo is back, taking on Manhattan--and Shady Hills, New Jersey--on the hunt for a killer in disguise.
After her last brush with murder landed her in People magazine, Jane is eager to get back to a life of reading proposals, making deals, and throwing a birthday party for her son at a local inn. But before anyone can even say "make a wish," the body of an unknown young woman is found hanging in the woods behind the inn.

Jane knows the only way she can shake the gruesome murder out of her mind is to keep busy. So when editor Holly Griffin gives her the chance to represent Goddess, the world's hottest new pop star, Jane is grateful for the distraction...until Holly is found dead, stabbed with a letter opener.

Determined to solve both murders, Jane, along with the help of Winky, starts snooping around, uncovering a scandalous secret that someone will do anything to keep buried...
