However, at the end of half an hour when we seemed to be getting
no further along, Kennedy did not protest at her desire to leave
us, "to keep a date," as she expressed it.

"Waiter, the check, please," ordered Kennedy leisurely.

When he received it, he seemed to be in no great hurry to pay it,
but went over one item after another, then added up the footing
again.

"Strange how some of these waiters grow rich?" Craig remarked
finally with a gay smile.

The idea of waiters and money quickly brought some petty
reminiscences to her mind. While she was still talking, Craig
casually pulled a pencil out of his pocket and scribbled some
figures on the back of the waiter's check.

From where I was sitting beside him, I could see that he had
written some figures similar to the following:

5183 47395 654726 2964375 47293815 924738651 2146073859

"Here's a stunt," he remarked, breaking into the conversation at a
convenient point. "Can you repeat these numbers after me?"

Without waiting for her to make excuse, he said quickly "5183."
"5183," she repeated mechanically.
