Evidently something very serious had happened.
My first impulse was to hasten to the Grosvenor Hotel, engage a room
there, and try to discover something of the cause which had brought
about Madame Gabrielle's sudden flight. Perhaps my anxiety for her
safety operated more powerfully than I ought to have allowed. In our
business personalities are nothing; it is the end that counts.
A moment's reflection showed me that in taking this course I should
simply be playing into the enemy's hands. I was too well known. I
hoped that my presence in England was not suspected by the German
agents, and if I ventured to stay at the Grosvenor they would certainly
very soon have me under close observation.
By using the official telephone between London and Paris I managed to
get into communication with Madame Gabrielle at her flat in the
Boulevard Pereire, and soon learnt the reason for her flight. Van Rosen
had discovered her, and was watching her closely.
Here, indeed, was an antagonist worthy of my steel! I had long known--
and so far as his abilities went, had respected--van Rosen as one of the
cleverest agents of the Koniggratzer-strasse. He was able to pose as an
Englishman--a rare accomplishment in a German--for he had been educated
at Haileybury, and had been in England off and on since his youth. He
was now living in a north-western suburb, where he posed as Mr George
Huggon-Rose, a solicitor who had retired from practice. Only British
apathy made this possible. A moment's investigation would have shown
that the man could not have been what he pretended, for no such retired
solicitor as Mr George Huggon-Rose was known to the Law Society.
As a matter of fact, it was through this very slip on his part that I
had "spotted" van Rosen. We had suddenly lost sight of him a year or
two before, and try as we would--for we knew that wherever he might be
he would be dangerous--we could not locate him. The accident which led
to his discovery was curious. I had been spending a few days in North
London, and one morning stopped at the railway bookstall to buy a paper.
As I approached the stall a tall, gentlemanly looking man, who had been
chatting with the clerk, turned away and entered the train. Something
about him struck me as strangely familiar.
"Who is that gentleman?" I asked the man at the stall.
"Oh," he replied, "that's Mr Huggon-Rose. He used to be a solicitor in
the City, but he retired and has been living here for a year or two."
But I was not quite satisfied; some odd memory, in which I felt sure Mr
Huggon-Rose was concerned, haunted me all the way to town, and I could
not shake it off. I had only seen van Rosen once, though I had had a
good deal of experience, and it was not surprising that I failed to
recognise him. When I got up to town I consulted the _Law List_, but
could find no trace of Mr Huggon-Rose.
Then I became more suspicious, and before many days were over I had
succeeded in definitely identifying Mr Huggon-Rose with one of the
Kaiser's cleverest spies. Thus the mystery of van Rosen's disappearance
was solved by his own slip. If, when I looked up the _Law List_, I had
found Mr Huggon-Rose's name and address duly set out, I should probably
have thought I had been deceived by some chance resemblance and wasted
no more time on the matter. How true it is that trifles make the sum of
life!
The position now was plainly serious: van Rosen's presence in London
boded no good. The man was as unscrupulous as he was clever. The
British contra-espionage department knew him well and had been greatly
chagrined at losing sight of him. Afterwards, in consequence of my
report to Hecq, he had been kept under close observation; but we had
never been able to secure sufficient proof to justify his arrest, strong
though our suspicions were. He had evidently been walking very warily
since the outbreak of war. Unfortunately he had adopted that easiest of
all cloaks of the German spy, and had become a naturalised Englishman
just before war broke out. But the adage "Once a German always a
German" applied with special force to van Rosen.
After speaking with Madame Gabrielle I had a long chat with Hecq over
the private wire, and together we mapped out a pretty comprehensive plan
of campaign, in which both Aubert and Madame Gabrielle had very definite
parts to play.
Then the mysterious scented wedding card claimed my full attention, for
I was determined to sift its secret to the bottom. First, I paid a
visit to Somerset House, where I very thoroughly searched the records of
recent marriages. These showed me that no marriage had taken place
between persons named Wheatley and Easterbrook. A certain Agnes
Wheatley had been born in June, 1894, at Mina Road, Old Kent Road, in
the parish of St George the Martyr, Southwark, and there were records
of two James Easterbrooks. One was James Stanley Easterbrook, born in
Lord Street, Southport, in 1881; the other, James Henry Charlton
Easterbrook, had first seen the light of day in the village of
Forteviot, Perthshire, in 1870. The _Army List_, of course, failed to
show any Captain James Easterbrook, of the Royal Fusiliers.
All this did not carry me much farther. The father of the Southport
Easterbrook was apparently a prosperous Blackburn tradesman; but that of
the man born in Scotland was vaguely set down as of "no occupation," a
curious entry for a Scottish village, where practically everybody would
be likely to live by the labour of his hands, and where one would hardly
expect to find persons of leisured independence. The fact worried me.
But an inquiry at Forteviot showed that there had been no Easterbrooks
in the village for many years, and no one seemed to recollect anything
about them.
In order to conceal myself from the astute van Rosen, I had taken rooms
in a cheap boarding-house, full of old ladies, in Guilford Street,
Bloomsbury, and, equipped with a silver discharge badge and a set of
"faked" Army papers, posed as an invalided soldier recovering his health
before taking up work. I was thus able to disarm the inquisitive prying
of my fellow-boarders, and I am afraid I gave them some highly
remarkable "information" about the war and my share in it! If one is
engaged in spying or contra-espionage work one must be ever ready to
combat silly suspicions that give rise to endless gossip and to evade
unfriendly and malicious comment.
The enigma of the wedding card worried me incessantly. That the
prosperous Jules Cauvin was one of the puppets of Potsdam, and also that
he had betrayed France, I felt morally convinced. Hecq, indeed, held
documentary evidence of Cauvin's friendship with the Austrian
millionaire spy, Herr Jellinck. I knew, almost with certainty, that the
perfumed wedding card was intended to convey a message of some kind,
since in every particular it was clearly shown to be a bogus document.
Yet without more direct evidence Cauvin, had we ventured to arrest him,
must have slipped out of the clutches of the law. For, after all, mere
friendship or acquaintance with a spy, however suspicious, does not
prove the guilt of espionage.
Inquiries made by the British Special Branch soon showed that none of
the Easterbrooks in the British Army could by any possibility be
connected with the "Captain Easterbrook" of the wedding card.
Within a week I established the fact that Agnes Wheatley had died before
she reached the age of ten years. Therefore, she could not have been
the mysterious bride to whose "wedding" Jules Cauvin and his wife had
been invited. I was thus thrown back on the two Easterbrooks, and for
the next few days, if I may use the term, I breakfasted, lunched, and
dined on Easterbrooks! And helping in my quest were some of the
smartest men of the British Special Branch.
Six weeks went by--weeks of feverish activity and incessant patient
investigation. That mysterious wedding card, with its pungent odour of
stag-leaved geranium, hypnotised me, and I could think of nothing else.
And everything began to seem so hopeless that even the Scotland Yard
men, most unrelenting and unwearying searchers-out of hidden mysteries,
began to get depressed and to fancy they were hopelessly beaten.
Van Rosen, of course, was under constant surveillance. Whether he
suspected it or not I do not know, but for the time being he seemed to
have entirely abandoned his usual business. He went about quite openly,
and I often wondered whether he was tacitly defying us. Probably his
work was so far advanced that he could afford to wait, and hoped to
disarm suspicion by the very openness of everything he did. Had there
been any real necessity we could, of course, have arrested him on some
charge or another, but we still hoped that by giving him plenty of
latitude we should sooner or later stumble on some valuable information.
