In the distance we saw the bright-white light of an approaching
airship, but we attached no special significance to so common a sight.
Like a bolt of lightning it raced toward Helium until its very speed
bespoke the unusual.
Flashing the signals which proclaimed it a dispatch bearer for the
jeddak, it circled impatiently awaiting the tardy patrol boat which
must convoy it to the palace docks.
Ten minutes after it touched at the palace a message called me to the
council chamber, which I found filling with the members of that body.
On the raised platform of the throne was Tardos Mors, pacing back and
forth with tense-drawn face. When all were in their seats he turned
toward us.
"This morning," he said, "word reached the several governments of
Barsoom that the keeper of the atmosphere plant had made no wireless
report for two days, nor had almost ceaseless calls upon him from a
score of capitals elicited a sign of response.
"The ambassadors of the other nations asked us to take the matter in
hand and hasten the assistant keeper to the plant. All day a thousand
cruisers have been searching for him until just now one of them returns
bearing his dead body, which was found in the pits beneath his house
horribly mutilated by some assassin.
"I do not need to tell you what this means to Barsoom. It would take
months to penetrate those mighty walls, in fact the work has already
commenced, and there would be little to fear were the engine of the
pumping plant to run as it should and as they all have for hundreds of
years now; but the worst, we fear, has happened. The instruments show
a rapidly decreasing air pressure on all parts of Barsoom--the engine
has stopped."
