"That is another thing which it is impossible to make sure of at this time," replied Ashton-Kirk. "But, merely as a suggestion, mind you, I recall that the' Bounder' visited her on the night it happened."

"He struck her, you mean!" Bat's hands clenched and his great shoulders heaved. "The infernal cur! that would be just like him!"

"Another suggestion which I'd like to make," spoke Ashton-Kirk, "is one which may or may not be significant. The maid said Miss Cavanaugh put her jewels in a bank vault the morning after his visit."

Bat Scanlon stiffened up; an exclamation upon his lips; one fist smacked into an open palm as he cried:

"You've hit it! She just came in from the theatre, and she was wearing the diamonds. When she refused him money he grabbed them; she resisted and he struck her!"

"You may be correct," said the investigator. He was keen, calm, impersonal; it was as though the entire matter were a game, the intricate possibilities of which were just being uncovered. But Scanlon was much excited; the more the thing grew and took shape in his mind, the more agitated he became. "And if you are right," proceeded Ashton-Kirk, "we can perhaps guess as to what followed."

Something like a shudder ran through Scanlon's big frame.

"I know what you mean," he said. "That thing has been lying like a shadow across my mind from the beginning. Nora Cavanaugh is a woman of spirit; the man who struck her would risk——"

But the other interrupted him.

"We'll not think of shadows," said he, quietly. "They will land us nowhere. What we are going to do is light the lamps along the road this thing leads us; in that way only can we get a good look at the facts."
