'Yes; give me the address of the shop in Tottenham Court Road. Do you happen to have about you one of those new five-shilling pieces which you believe to be illegally coined?'
He opened his pocket-book, took out the bit of white metal, and handed it to me.
'I'm going to pass this off before evening,' I said, putting it in my pocket, 'and I hope none of your men will arrest me.'
'That's all right,' laughed Hale as he took his leave.
At half-past three Podgers was waiting for me, and opened the front door as I came up the steps, thus saving me the necessity of ringing. The house seemed strangely quiet. The French cook was evidently down in the basement, and we had probably all the upper part to ourselves, unless Summertrees was in his study, which I doubted. Podgers led me directly upstairs to the clerk's room on the third floor, walking on tiptoe, with an elephantine air of silence and secrecy combined, which struck me as unnecessary.
'I will make an examination of this room,' I said. 'Kindly wait for me down by the door of the study.'
The bedroom proved to be of respectable size when one considers the smallness of the house. The bed was all nicely made up, and there were two chairs in the room, but the usual washstand and swing-mirror were not visible. However, seeing a curtain at the farther end of the room, I drew it aside, and found, as I expected, a fixed lavatory in an alcove of perhaps four feet deep by five in width. As the room was about fifteen feet wide, this left two-thirds of the space unaccounted for. A moment later, I opened a door which exhibited a closet filled with clothes hanging on hooks. This left a space of five feet between the clothes closet and the lavatory. I thought at first that the entrance to the secret stairway must have issued from the lavatory, but examining the boards closely, although they sounded hollow to the knuckles, they were quite evidently plain matchboarding, and not a concealed door. The entrance to the stairway, therefore, must issue from the clothes closet. The right hand wall proved similar to the matchboarding of the lavatory as far as the casual eye or touch was concerned, but I saw at once it was a door. The latch turned out to be somewhat ingeniously operated by one of the hooks which held a pair of old trousers. I found that the hook, if pressed upward, allowed the door to swing outward, over the stairhead. Descending to the second floor, a similar latch let me in to a similar clothes closet in the room beneath. The two rooms were identical in size, one directly above the other, the only difference being that the lower room door gave into the study, instead of into the hall, as was the case with the upper chamber.
The study was extremely neat, either not much used, or the abode of a very methodical man. There was nothing on the table except a pile of that morning's papers. I walked to the farther end, turned the key in the lock, and came out upon the astonished Podgers.
'Well, I'm blowed!' exclaimed he.
'Quite so,' I rejoined, 'you've been tiptoeing past an empty room for the last two weeks. Now, if you'll come with me, Podgers, I'll show you how the trick is done.'
