“Good! Watch him carefully. We’ll be up to them in about five minutes.”

The Gull was swiftly slipping through the water. In a little while it was almost abeam of the craft towing the mysterious motor boat. Frank threw her head up into the wind, and, as he did so a voice from the other sailboat hailed him.
“Gull ahoy! Are you trailing us?”
It was the mysterious man calling, and he was standing on the rail.
“Yes, we are,” answered Frank boldly.
