*Strange Shadows*

 Cecile and Marie Grace were chatting on the porch when a strange shadow quickly whizzed by.

"Oh! What was that?" Cecile asked startled.

"WHO was that?" Marie Grace responded.

"It looked like a thin figure with a hat on." Cecile said.

"Shh. What if it comes back? Let's go inside" Marie Grace said hurriedly.

What do you think they saw?
