The sun now was directly overhead and Penny and Louise knew that they were expected at their homes for luncheon. Thanking Sara for her services, they sailed on to their own dock. As they hastened through the park to a bus line, Penny remarked that it would be fun sometime to visit Noah and his ark.
“Well, perhaps,” Louise rejoined without a great deal of enthusiasm.
The buses were off schedule and for a long while the girls waited impatiently at the street corner. Penny was gazing absently toward a cafe nearby when a short, untidy man with shaggy gray hair, came out of the building.
“Why, isn’t that Mr. Oaks, the bridge watchman?” she asked her chum.
“It looks like him.”
From far up the street an approaching bus could be seen, but Penny had lost all interest in boarding it.
“Louise, let’s talk to Mr. Oaks,” she urged, starting toward him.
“But we’ll miss our bus.”
“Who cares about that?” Penny took Louise firmly by an elbow, pulling her along. “We may not have another chance to see Mr. Oaks. I want to ask him why he identified the saboteur as Sara Ottman’s brother.”
