"Where?"
"Let me see—you'll have to come at once, because I am leaving town this afternoon. Suppose you come to the Hotel Bienvenu, and meet me in the main lobby."
"Half an hour," Jack whispered to Mrs. Cleaver.
"I'll come just as soon as I can dress," she said over the 'phone. "Can you give me half an hour?"
"Very well. I shall expect you in half an hour."
Jack's heart beat high with hope. He immediately called up police headquarters and got the Third Deputy Commissioner on the wire. After identifying himself to that individual, he asked to have a plainclothes man meet him in the bar of the Hotel Bienvenu in twenty minutes time, to make an arrest. The Deputy Commissioner said he would bring the man up himself, so there could be no possibility of missing Jack.
To Mrs. Cleaver Jack said: "I will go to the Bienvenu now and wait for my men. You leave here in precisely twenty-five minutes. Have your chauffeur let you out at the side door of the Bienvenu, and then walk around by the street to the front door. This will bring you past the windows of the bar, and will give me a chance to point you out to my policeman. Then I'll send him up into the lobby, and I can remain in the background. He will arrive in the lobby at the same moment with you."
All the preliminaries passed off as Jack had planned. The Deputy Commissioner and the plainclothes man turned up in the bar of the Bienvenu at the very moment of the time appointed. They took up their post at a window, and sure enough in five minutes Mrs. Cleaver swam past their ken, regal and languid in her silver fox furs.
"That's the woman," Jack said to the policeman. "Mark her well. Now go up into the lobby. As you get there she will just be coming in the front door. Watch who approaches her. Arrest the man with whom she gets in conversation. He's supposed to be an elderly man, short, stocky, with gray hair brushed forward of his ears, gray mustache and Imperial. But he may be disguised. Arrest any man that goes up to her and engages her in conversation. Watch yourself well, for he's a desperate character."
"We'll wait down here," added the Deputy Commissioner. "If you need help blow your whistle."
