One Strike Too Many — D.R. Meredith

With a lifetime bowling average of sixty-nine, Maude Turner was not an aficionado of the sport. In fact, given the choice between watching a bowling tournament and throwing herself into an erupting volcano, she might reconsider her stand against self-immolation. But duty calls. Her brother-in-law Victor Jamison is the star of his bowling team and it is Maude's duty to support Victor and the other members of the Senior Citizens Center League. Also, there is the problem of the voracious three-time widow, Camilla, who is trolling for Victor. But Camilla turns out not to be the problem. Murder is. When the automatic return regurgitates Victor's bowling ball covered in blood, Maude knows it's time to do a little trolling of her own: for a cold-blooded killer.
