The Senior Sleuths


"The Senior Sleuths," Book One, Dead In Bed (February, 2018); Book Two, Dead In Seat 4-A (February, 2019); Book Three, Dead in THAT Beach House (coming 2020).

Like Nick and Nora Charles from "The Thin Man" series, Dick and Dora Zimmerman from, "The Senior Sleuths," solve crimes, especially murder such as when a dead body is found in an icebox with a note that says, "contents rotten."

Still in their early sixties, the Zimmerman's not only have the time—but the money, the smarts and the "chutzpa"—to get involved even when they are warned by police and criminals to stay away. Moreover, other condo residents where they live in Manhattan and Vegas seek Dick and Dora's help whenever they suspect any foul play!

They have great cohorts like Zero the Bookie, Frankie Socks and even 89-year old Bertie Gladstone who helps them catch the murders. Dick and Dora often mix wit and humor when facing danger...and solving murders.

Dead in Seat 4-A

Why was the man in seat 4-A murdered?
The Las Vegas sheriff is not happy to have Dick and Dora back in town, especially since they arrived on a plane with a dead body. When the senior sleuthing couple is around, trouble is not far behind. 

When Dora is kidnapped and taken to The Mob Museum along with Zero’s new girlfriend, who he only just met on an online gambling site, Dick and his cohorts embark on a frantic journey to get them back. Along the way they meet a dangerous cast of characters ranging from cheats and embezzlers to cold blooded killers. For Dick and Dora, the race is on to catch a murderer before someone else becomes a victim.

When an alarm goes off at the Skyline Vista Condos, a posh high-rise building for the active and engaging senior set, a body is found...Dead in Bed. When police are left with little evidence to find the killer, the adventure begins for our Senior Sleuths. Dick and Dora Zimmerman follow the clues through New York neighborhoods from Lower Manhattan to the Meatpacking District to Brooklyn before the trail turns cold and a killer gets away with the goods. 


Dead in THAT Beach House

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...

"This series is the senior version of Nick and Nora Charles, with a humorous touch, a splash of noir, cracker-jack sleuthing, unusual, captivating characters, and fascinating mysteries.

 Marilyn Meredith, Author of the Deputy Tempe Crabtree Mysteries.


“The Senior Sleuths” Mysteries are unique! They take a different look at the crime of murder and especially, at the elderly sleuths - not that Dick and Dora Zimmerman are old.  They are mature, well-funded adults, not typical of the traditional Private I, or police detective. That is what makes their machinations so intriguing. “The Senior Sleuths” Mysteries present a distinctly original approach. For those who love ‘murder and mayhem,’ A Must Read.”

 Elizabeth Cooke, Author of 14 books including Paris Hotel Series, Rose Trilogy and Abbi’s Forever Home 


"Dick and Dora Zimmerman and their motley crew of friends and business associates will keep you smiling and guessing "whodunnit" until you turn the last page."  

 Terry Lucas, Library Director and Former Bookstore Owner 


"Reading Dead in Bed, the first twisty and fast-paced book in Rosen's new mystery series,The Senior Sleuths, I found myself laughing and biting my nails at the same time. Sure, her characters Dick and Dora Zimmerman are no spring chickens, but they're every bit as feisty and resourceful as her younger detectives in her Dying to be Beautiful series.  The mayhem begins when the "Zimms," along with their cohorts--- Zero the bookie, Bertie the flirt and a host of others-- find a stranger with a knife plunged in his chest in apartment 506 of their upscale Manhattan condo complex. They're determined to solve this murder mystery as well as other mindboggling crimes they run into along the way. What a ride!"
