number you got from the girl at the telegraph company?" Toffee asked. "Positive," Marc replied. "Well, we can be sure of one thing, at least. Mayes wouldn't be living here. I'll bet he's never even seen this part of town." A small frown creased his forehead. "Maybe it's just another run around. Maybe Ruby sent the wires; she could have easily.
