The Obnoxious Oilman — Mathiya Adams

When Neela Woods, a well-known international travel blogger goes missing, her family assumes she's just on another jaunt. But her partner suspects foul play, specifically the Obnoxious Oilman who the blogger has been dating.
The stakes are high. Neela not only comes from money...her Ranch in Elbert County may be worth over a million dollars in oil and gas rights. When MacFarland finds Neela's body in a bat cave, he also finds that he has plenty of suspects, any one of whom had reason and opportunity to kill the young woman.
The Obnoxious Oilman is the fifteenth book in the Hot Dog Detective series. Each book can be read independently, but if you want to read them in order, just follow the alphabet.
