"How were you going to do this?"

"I know your servant or chum, Mr Pentana. I've lent him money: and Peter Petroff, the Prince's particular servant, gambles like a lord, and he owes me and a friend of mine a lot of money. We were going to work through them."

"It is enough; and well for you that you have answered truthfully. Now tell me: do you know how to use a revolver?"

"Never fired a shot in my life."

Phadrig went to the secretaire and took a common, cheap revolver, identical with thousands of others which our criminally careless Government allows to be bought every day without the production of a licence—just a hooligan's weapon, in fact—went back and put it into the Jew's hand. He raised the hand several times, and pointed the muzzle to the temple, keeping the forefinger on the trigger. At length he let go the wrist, and said in a gentle, persuading tone:

"That is the way to handle a revolver when you are going to shoot, my dear Josephus. Now, let me see if you can do it by yourself."

With mechanical precision the Jew's arm went up until the muzzle touched his temple. Again and again he did the same thing at Phadrig's bidding, till at length he said rather more peremptorily:

"Now pull the trigger!"

The finger tightened and the hammer clicked. Five times more was the operation repeated, and then Phadrig gently took the revolver and laid the hand down. He went to the secretaire and loaded the six chambers, cocked the weapon and put it into the right hand side-pocket of the lounge jacket which Josephus was wearing, and said deliberately:

"Now remember, my dear Josephus: you will go straight back to your office in Waterloo Road and let yourself in with your key. In your private room you will see a man who wants to rob you of some valuable papers. You will be ruined if he gets them, so you must take your pistol out of your pocket and shoot him. Do you quite understand me?"
