Arthur kept his voice calm, almost casual. “I wanted to let you know I’ll be cleaning up my pool. The water’s gotten dirty. I’ll be turning off the pump for a while, and I’ll be using stronger chemicals to balance it out.”
“If it wasn’t you using the pool, then this isn’t your concern, but I thought I should give you a heads up.” The husband rolled his eyes. “Why are you telling us this?” Arthur cleared his throat. “Because if anyone did decide to use the pool, it wouldn’t be safe for them afterward.”
