This is an early Sharon McCone mystery--she's still at All Souls Cooperative--but since she's away in the CA Delta area there's very little interaction with other continuing characters. However, her younger sister Patsy & her kids play a prominent part in the story. The bulk of the story is an armchair type mystery, but there are also some action scenes including a big one at the end. The mystery slowly unfolds. I found the motive easier to determine than the culprit. There are some sub-plots, but Muller eventually weaves it all together into a neat package. You CAN figure out the perpetrator near the end (before its revealed by McCone), but it's not easy. Overall, this is a solid Muller mystery which stands the test of time. It does remind me a bit of Agatha's 10 Little Indians to a degree. By the way, Muller also wrote 2 mystery trilogies starring 2 different heroines: Elena Oliverez (The Tree of Death, The Legend of the Slain Soldiers, Beyond the Grave) & Joanna Stark (Dark Star, The Cavalier in White, There Hangs the Knife).
