From the back:
Three clients in two days, the PI business in Pigeon Fork, KY, sure was picking up...
First came Ruta Lippton, owner of the curl Crazee hair salon, who said her house was "broken-and-entered."
Winslow Reed, an ex-nerd who was now married to ex-cheerleader June Jacoby told the same story. Both Winslow and Ruta lived in the fancy new subdivision called Twelve Oaks, and both claimed ht sheriff wasn't taking them seriously, on account of how noting had actually been -stolen-.
Last came nasal-voiced, horse-faced Phyllis Carver. Nothing was missing from her place either, but then poor Phyllis didn't have much to take.
I was shocked when June and Ruta suddenly called me off the case. But shock didn't begin to describe how I felt when I headed back out to Phyllis' and found her shot dead. Near her body was a scarp of paper with a single number seven scrawled n it, which, as clues went, was pretty pitiful. Then, while I was waiting for the sheriff, I found the three tape recorders.
One still had a tape in it - a recording of Phyllis' husband Orval and a woman who definitely was not Phyllis. IN bed. Having a real good time. That made Orval a prime suspect, but I still didn't know what them other two tape recorders were doing in Phyllis' kitchen cupboard, and what the heck Phyllis meant by that number seven...
