“She’s having a hard time getting back. Do you think she’s all right?” Arden asked anxiously.
“Wait—” Terry cautioned—“I’m not sure——”
Sim was still swimming but seemed to be tiring. She turned over on her back for a brief rest and began again. But it seemed no use. Apparently she was caught in a sea-puss and was still making no headway.
Terrified, Terry and Arden looked at each other, unable to utter a word. In that instant a figure flashed by them and disappeared with a splash in the waves. Still speechless, they both knew——
It was Melissa!
She was going to help Sim to safety. The girls watching on the beach felt the relief so suddenly and so completely that each grasped the other.
“Melissa!” breathed Terry.
“She’ll get her,” answered Arden.
What little they had done to make friends with the girl came now in a rush of grateful memory.
Yes, Melissa would help them. She was their friend.
