Two days later Tarzan reached Algiers. There he found that he would
have a two days' wait before he could catch a ship bound for Cape
Town. He occupied his time in writing out a full report of his
mission. The secret papers he had taken from Rokoff he did not
inclose, for he did not dare trust them out of his own possession
until he had been authorized to turn them over to another agent,
or himself return to Paris with them.

As Tarzan boarded his ship after what seemed a most tedious wait to
him, two men watched him from an upper deck. Both were fashionably
dressed and smooth shaven. The taller of the two had sandy hair,
but his eyebrows were very black. Later in the day they chanced
to meet Tarzan on deck, but as one hurriedly called his companion's
attention to something at sea their faces were turned from Tarzan
as he passed, so that he did not notice their features. In fact,
he had paid no attention to them at all.

Following the instructions of his chief, Tarzan had booked his
passage under an assumed name--John Caldwell, London. He did not
understand the necessity of this, and it caused him considerable
speculation. He wondered what role he was to play in Cape Town.

"Well," he thought, "thank Heaven that I am rid of Rokoff. He
was commencing to annoy me. I wonder if I am really becoming so
civilized that presently I shall develop a set of nerves. He would
give them to me if any one could, for he does not fight fair. One
never knows through what new agency he is going to strike. It is
as though Numa, the lion, had induced Tantor, the elephant, and
Histah, the snake, to join him in attempting to kill me. I would
then never have known what minute, or by whom, I was to be attacked
