“Yes. It was a man in a diving rig. He’d taken off the helmet. Now, what do you think of that?”

Quite out of breath, the blonde haired little French girl dropped down upon a berth at the side of the cabin.

“Man in a diving suit.” Florence spoke in a matter-of-fact tone. “Going to dive, of course.”

“But why?”

“That’s right. Why?” Florence’s brow wrinkled.

“I wish—” she said slowly after a period of silence, “wish they hadn’t come.”

She was to wish this many times in the days that were to follow. And then she was to change her mind.
