Massey received them in the study, his right hand swathed in bandages, and his left arm in a sling.

“If I had followed my own inclination,” he said, “I should have sent for you at first. I was persuaded to place the matter in the hands of the police, but although they have been searching and investigating and inquiring and cross-examining for just a week, they’re as far as ever from discovering any clew to the identity of the scoundrels. I sincerely trust you will be more successful.”

The detective looked a little dubious.

“You haven’t improved my chances by waiting a week before sending for me. However, I’ll do my best, of course. Needless to say, I’ve read the newspaper accounts[Pg 28] of the case, but I should be glad to hear your version of the affair.”

“If you’ve read the newspapers,” replied Massey, “I don’t suppose I can tell you anything that will be very new. We’d been to the opera—my wife and daughters and myself—and, in the ordinary course of events, we should have returned about half past twelve. Owing to engine troubles and a blow-out, however, it was just after two when we got here.

“We were all rather tired,” he continued, “and we decided to go straight to bed. Before my wife and daughters retired, however, they handed me their jewels. I placed the latter in their proper cases, brought them to this room, and locked them in that safe.”

He pointed to the mutilated safe in the corner. It was empty now, but was otherwise in the same condition as when the burglars had left it.

“After I’d locked up the jewels,” Massey resumed, “I switched off the lights and went to bed. For some reason or other I could not get to sleep at once, and when I’d been in bed about half an hour I thought I heard somebody moving in the study. I got up quietly, put on a dressing gown and slippers, armed myself with a revolver, and stole downstairs.

“When I’d crept up to the door here,” he went on, “I distinctly heard men at work in the room. I waited for a few seconds, and then I suddenly flung the door open and sprang in, switching on the lights as I did so. One glance showed me that the safe had been forced and the jewels removed. Two men were about to stow the cases in a leather bag, and two others were packing up the apparatus with which they had opened the safe.”

“All the four men wore masks, I understand,” Nick put in.
