"Once. When—" She paused.

"Yes. Last Wednesday night, when you came over to ask those questions about pure science. What happened then?"

"We went to a place to dance."

"And that's the reason, I suppose," rumbled the Doctor sardonically, "that I found you wandering about the streets in a table cloth, step-ins, and a pair of hose! That's why I found you on the verge of passing out from rotten liquor, and looking like the loser of a battle with an airplane propellor! What happened to your face?"

"My face? What's wrong with it?"

The Doctor rose from his chair and seized the hand-mirror from her dressing table.

"Look at it!" he commanded, passing her the glass.

Pat gazed incredulously at the reflection the surface presented; a dark bruise colored her cheek, her lips were swollen and discolored, and her chin bore a jagged scratch. She stared at the injuries in horror.

"Your knees are skinned, too," said Horker. "Both of them."

Pat slipped one pajamaed limb from the covers, drawing the pants-leg up for inspection. She gasped in startled fright at the great red stain on her knee.
