'Edith,' said Bruce, 'I'm rather worried about Raggett.'
'Are you? Why?'
'Well, the last time I met him, he came up and asked me if I knew the difference between a sardine and a hedgehog. Of course I said no, thinking it was some riddle, but he only answered, "Then you must be a fool!"'
Edith smiled.
'Is that all?'
'No, it is not all. It will give you a shock, what I'm going to tell you now. At the office—at the office, mind—I received a letter from Raggett, written on a crumpet.'
'On a what?'
'On a crumpet. The letter was gummed on; the thing had a stamp, and was properly addressed to me, and it came through the post. The note itself was quite rational, but the postscript—what do you suppose the postscript said?'
'I can't think.'
'It said, "PS—Please excuse my writing to you on a crumpet, as I haven't a muffin!"'
