"No, my dear sir. Quite normal under the circumstances. Severe shock to the nervous system. Loss of memory proceeds nearly always on the same lines. I suggested a specialist, of course. There's a very good man in Paris—makes a study of these cases—but Mrs. Vandemeyer opposed the idea of publicity that might result from such a course."

"I can imagine she would," said Sir James grimly.

"I fell in with her views. There is a certain notoriety given to these cases. And the girl was very young—nineteen, I believe. It seemed a pity that her infirmity should be talked about—might damage her prospects. Besides, there is no special treatment to pursue in such cases. It is really a matter of waiting."

"Waiting?"

"Yes, sooner or later, the memory will return—as suddenly as it went. But in, all probability the girl will have entirely forgotten the intervening period, and will take up life where she left off—at the sinking of the Lusitania."

"And when do you expect this to happen?"

The doctor shrugged his shoulders.

"Ah, that I cannot say. Sometimes it is a matter of months, sometimes it has been known to be as long as twenty years! Sometimes another shock does the trick. One restores what the other took away."

"Another shock, eh?" said Julius thoughtfully.
