Title: Dead in THAT Beach House: A Senior Sleuths Mystery
Publisher: Level Best Books (2020)
Genre: Mystery

Once we had arrived in the Hamptons, settled in and I felt comfortable, I began to add small amounts of poison to the evening cocktails. It was from the oleander flowers. I had planted them carefully behind the barn in Ames. After only weeks, they were falling ill, listless, crying to go back to Ames. They felt too sick at the beach house. It was simple.
I know you must think I’m a monster. But, really, they felt very little when I strangled them to death thanks to the poison in their system. When they were dead, I filled my library with books about murder and witchcraft. The note I leave for whomever might find them might explain what happened…

The Senior Sleuths, Dick and Dora Zimmerman, much like Nick and Nora Charles from the Thin Man series, and their cozy group of interesting, quirky friends take on crooks and murderers while dealing with an outrageous case of elder abuse.

Title: The Gourmet Gangster: Mysteries and Menus
Co-author: Jory Rosen
Publisher: Level Best Books (2019)
Genre: Mystery

The mysteries are malicious. The recipes are delicious. John Klopfenstein, Criminal Defense Attorney, Carmel/Salinas, California. The Gourmet Gangster is a labor of love, a Mother – Son collaboration of short stories paired with mouth-watering recipes, inspired by their shared family experiences. Marcia and Jory Rosen have selected the perfect menu to accompany their tales of murder, mayhem, and the Mob, told through the eyes of a gangster’s daughter. Their father and grandfather was a bookie and owner of a successful gambling spot. When he was ready to move on from that life, he opened a bar-restaurant in the heart of Main Street in Buffalo, New York. His love of food was a great influence on his family, particularly his daughter, Marcia, and grandson, Jory, who continue that tradition through these stories and recipes. A sampling of recipes in The Gourmet Gangster include Chicken Piccata Caper, The Sacrificial Lamb, Fowl Play, and The Quiche (Kiss) of Death. We suggest pairing them with the stories “Recipes for Murder,” “Malled to Death,” “He’s a Dead Duck,” and “Make Mine Murder.” Bon Appetite!
