'This is the nursery,' said a manly voice. 'Ah, locked! I quite understood from the agent that the keys were in the hall.'

Of course we had the keys, and this was the moment that Noël chose for dropping them. Why he was fingering them where they lay on the mantelpiece the author does not know, and never will know. There is something about 'previously demented' in some Latin chap—Virgil or Lucretius—that seems to hit the nail on the head. The keys fell on the cracked hearthstone with a clang that Oswald, at any rate, will never forget.

There was an awful silence—quite a long one.

Then another voice said:

'There's someone in there.'

'Look at that bench,' said the other man; 'it's coiners' work, that's what it is, but there's nobody there. The keys must have blown down!'

The two voices talked some time, but we could not hear all their conversation. We were all wondering, as it turned out afterwards, what exactly the utmost rigour of the law was. Because, of course, we knew we were trespassers of the very deepest dye, even if we could prove that we were not real coiners.

'No,' we heard one of them say, 'if we go for the police very likely the gang will return and destroy everything. There's no one here now. Let's secure the evidence. We can easily break the door down.'

It is a sickening feeling when the evidence against you is going to be secured, and you don't know what the punishment for coining is, or whether anyone will believe you if you say you were only playing at it.

We exchanged pallid glances.
