A raven-haired girl walked into a doctor's office, one afternoon. The receptionist recognized her.

"Miss Brown! How are you doing, dear?"

"Much better, thank you. I've got a 2:00PM appointment with Dr Fishman."

"Of course. He should be ready, soon. Sit down and relax, a bit."

"Thank you."

She sat and read a Good Housekeeping. At 1:55, the receptionist said, "Miss Brown?"

She got up.

"Follow me, dear."

She led her to one of the examining rooms. She left, and Miss Brown wad in the chair and waited. A few minutes later, the doctor came.

"Hello, Miss Brown! Lovely to see you, again." They shook hands. "How's your foot?"

"Much better, thank you."

("Hi, 99," he whispered. "Do you have the information?"

"Yes, 65," she whispered back.)

She took her left shoe and sock off and put her foot in his lap. He studied it.

"I see your ingrown toenail has nicely heeled. Does it still cause any problems?"

"Not any more, Doctor. I've followed your advice and go barefooted whenever I can."

""Good girl! Well, let me clean the area."

He opened a glass bottle. Then he picked up a towel and poured some of the bottle's liquid onto it. Next, he wiped Miss Brown's foot with it.

(The name CHARLES SELFRIDGE magically appeared on the side of her foot.

"Are you absolutely sure, 99?," he whispered.

"Yes, 65," she whispered back. "A real shame."

He nodded. "Yes. I'll take care of it, myself. OK, this will get rid of the writing."

He opened another bottle and poured some of it onto another towel. He wiped this on her foot, and the name disappeared.)

"Well, I would say your toenail has healed enough so you don't have to see me again for it."

"I'm glad to here that."

He gave her a dry cloth, and she dried her foot off. She put her shoe and sock back on, and they got up together.

"Well, it was very nice seeing you again, Miss Brown."

"Nice seeing you too, Dr Fishman."

("Good luck, 65," she whispered.

"Thanks, 99.")

She left the office.

A few days later, a double agent named Charles Selfridge was found dead!
