"I want to find out where the locket and chain is that Sir Rupert wrenched off his wife's neck."

[CHAPTER XIX.]

WHAT DOWKER DISCOVERED.

After hearing the revelations made by Lord Calliston and Myles Desmond, concerning the movements of Sir Rupert Balscombe on the night of the murder, Dowker had no doubt in his own mind that the baronet was guilty of the crime. Rumour speaking truly for once said they lived unhappily together owing to Lady Balscombe's numerous infidelities, and it was only the honour of his name that prevented Sir Rupert applying for a divorce. Now, however, he had done so, as his wife's apparent flight with Lard Calliston was of too glaring a character to be overlooked even by the most complacent husband.

Dowker, however, did not believe in the genuineness of the application, merely looking upon it as a clever piece of acting on the part of a wily scoundrel to cloak his crime. In the detective's opinion Sir Rupert had simulated rage on hearing of his wife's apparent iniquity--had applied for a divorce knowing she was dead--and had gone down to the yacht with a full knowledge that he would not see Lady Balscombe. In fact, all through he had acted a very clever part, in order to ward off suspicion that he was guilty of the crime of murder.

What Dowker now wanted to find was the locket which Sir Rupert had wrenched off his wife's neck, and also the weapon used in the committal of the crime. It had been clearly shown that the Malay kriss taken from Cleopatra Villa could not have been used by anyone, so the baronet must have had some dagger of his own, which was now doubtless in his possession. If these two things could be found, their discovery coupled with the evidence of Calliston and Desmond would be quite sufficient to prove Sir Rupert guilty, unless, indeed, he could prove himself innocent, of which there did not seem to be much chance.

Dowker did not go at once to Park Lane as he was anxious to know how Lena Sarschine, or rather Lady Calliston, was after her hysterical confession of guilt, so he drove down to Cleopatra Villa, and on being shown in to the drawing-room was confronted by Lord Calliston. That young nobleman looked haggard and worn out, so that in spite of his conduct, which had led to the murder of one woman and the self-accusation of another, the detective felt sorry for him.

"What do you want now?" he asked irritably. "Have you come to arrest my wife?"

"Your wife," said Dowker, pretending to have heard this for the first time.

"Yes," replied Calliston, boldly; "we were married in France and she is now my wife. I don't believe her guilty of this crime--do you?"
