Royal Purple Murder (African Violet Club Mysteries #3)
Elise M. Stone

When an aging rodeo queen is shot dead at the annual Fourth of July Celebration, Lilliana Wentworth, retired librarian, African violet fancier, and amateur sleuth, must solve the case before a kindly, but somewhat ditzy friend is arrested for murder.
The village of Rainbow Ranch, Arizona is all abuzz since rodeo star Fox Fordyce came back to town. A genuine celebrity, the local newspaper gives her front page coverage, while the television stations run featured interviews.
When an elderly resident is found standing over the rodeo queen’s body holding a gun, the chief of police thinks this will be his easiest case to solve yet. But Lilliana isn’t so sure. She’s determined to prove the woman’s innocence, even while conceding she did have a motive. And means. And, apparently, opportunity.
The more questions Lilliana asks, the more suspects she comes up with. With the help of her own version of the Baker Street Irregulars, Lilliana peels back the layers of secrets. But will she be able to unravel the mystery before her friend is arrested?
