next visit to the capital Captain Naude was to
be informed of the formation of the new Committee, but for the rest
its very existence was to be kept a dead secret.

Mrs. van Warmelo told the members that she was in a position to
communicate with the President in Holland by every mail, and that the
methods employed by her would be revealed to them _after the war_.
With this they expressed themselves satisfied, willingly leaving the
matter of sending away dispatches from the field in Mrs. van Warmelo's
capable hands.

It was felt that the greatest responsibility resting on them at the
time was to have a suitable place of refuge ready to receive the
Captain when next he entered the town.

There was no house free from suspicion since the arrest of the
Committee, except--except--Harmony!

Harmony, surrounded as it was by British officers and their staffs, by
British troops and Military Mounted Police--Harmony was at last chosen

he came again, and in the meantime the Committee would be on the
look-out for an opportunity to send a warning and instructions out to
him not to approach the houses hitherto frequented by him.

For many weeks no spies belonging to his set came into town. No war

information, conveyed we know not how, of the safe arrival at the
Skurvebergen of young Els, the spy who had been fired upon and was
missing from his companions on that eventful September 12th. That this
news gave his relatives and friends great joy and relief after the
intense anxiety gone through on his account, my readers will readily
understand.

The discovery of the White Envelope was not always a source of unmixed
satisfaction.

One of them, containing news of the betrayal and arrest of the
Committee, and sent to Alphen in the ordinary way, failed to reach
its destination. This caused the senders so much anxiety that for some
time they did not dare risk the sending of another. The letter might
have fallen into the hands of the censors and the secret be discovered
by them, in which event they were probably waiting quietly to catch up
further information.

It may have been only a coincidence, but at this time the plott
