In a few moments the two friends were snugly ensconced in a clump of
bushes in a garden very near the entrance to the works. The grey car was
still occupied only by the chauffeur, but they could tell, by his
listening attitude and the expectant looks of the guards, that an
altercation of some sort was going on inside the guard-room.

"This is what I said, old man," Max went on in a voice which betrayed
his excitement:--

"TO HERR VON SCHENKENDORF, _alias_ OTTO SCHENK,

"I observe that you have at last accepted your dismissal from your
post as manager of the Durend works. You are going--hated and

nervous, jerky movements. He glanced quickly through it and sprang
uncontrollably to his feet, his face aflame with passion.

The officer at his side shouted to him in alarm and endeavoured to pull
him back into his seat.

Suddenly there was a loud clatter of horses' hoofs at the end of the
street, and a body of Belgian cavalry debouched into view. The chauffeur
of the grey car instantly started and turned his machine, and it moved
away with ever-increasing speed, Schenk still standing and gesticulating
wildly, with Max's letter clenched in his right hand, and the officer
endeavouring ineffectually to drag him back into his seat. As the car
passed the two watchers, they could not repress their exultation, but
jumped to their feet and gave a loud, full-throated British ch
