olumns headed 'Through German Glasses', and made the text of
articles showing what a good democrat he is becoming.

As I puzzled over the subject, certain conclusions began to form in my
mind. The four identical sentences seemed to hint that 'Deep Breathing'
had Boche affiliations. Here was a chance of communicating with the
enemy which would defy the argus-eyed gentlemen who examine the mails.
What was to hinder Mr A at one end writing an advertisement with a good
cipher in it, and the paper containing it getting into Germany by
Holland in three days? Herr B at the other end replied in the
_Frankfurter_, and a few days later shrewd editors and acute
Intelligence officers--and Mr A--were reading it in London, though only
Mr A knew what it really meant.

It struck me as a bright idea, the sort of simple thing that doesn't
occur to clever people, and very rarely to the Boche. I wished I was
not in the middle of a battle, for I would have had a try at
investigating the cipher myself. I wrote a long letter to Macgillivray
putting my case, and then went to sleep. When I awoke I reflected that
it was a pretty thin argument, and would have stopped the letter, if it
hadn't gone off early by a ration party.

After that things began very slowly to happen. The first was when
Hamilton, having gone to Boulogne to fetch some mess-stores, returned
with the startling news that he had seen Gresson. He had not heard his
name, but described him dramatically to me as the wee red-headed devil
that kicked Ecky Brockie's knee yon time in Glesca, sirr,' I recognized

Gresson, it appeared, was joy-riding. He was with a party of Labour
delegates who had been met by two officers and carried off in
chars-a-bancs. Hamilton reported from inquiries among his friends that
this kind of visitor came weekly. I thought it a very sensible notion
on the Government's part, but I wondered how Gresson had been selected.
I had hoped that Macgillivray had weeks ago made a long arm and quodded
him. Perhaps they had too little evidence to hang him, but he was the
blackest sort of suspect and should have been interned.

A week later I had occasion to be at G.H.Q. on business connected with
my new division. My friends in the Intelligence allowed me to use the
direct line to London, and I called up Macgillivray. For ten minutes I
had an exciting talk, for I had had no news from that quarter since I
