“Well?” he asked, and his hands were clenched upon the iron rail.

She did not answer. She stood staring at him with fixed eyes, and as she did so a sensation of annoyance passed across his mind.

“Ah!” he muttered. “You don’t love me. You’re only amusing yourself with me.”

“Rupert!” she exclaimed.

Seeing that his tactics were correct, he allowed his anger to develop. He made a dramatic gesture and flung himself back against the railing. At the same moment the paddle-wheel beneath him began suddenly to revolve, as the captain manœuvred the ship towards the shore. There was a slight lurch; Rupert uttered an exclamation; he seemed to sway away from her; and, heels over head, he fell into the churning water.

Muriel sprang forward. In the half-light she saw the soles of his shoes disappear as the black water swallowed him; then a dripping, writhing form was lifted on a blade of the paddle and tossed into the air. She saw his horrified eyes and his spread fingers. She heard him shriek....

“Help!” she screamed, and, screaming, she rushed across the deck. “Help! Help!”

[CHAPTER X—“FOR TOMORROW WE DIE”]

Amidst the wildest clamour the rowing-boat was launched, and two red-jerseyed native sailors took the oars, while a third, shouting and gesticulating, stood at the tiller holding up a hurricane-lamp. Just as they pushed off, Professor Hyley, carrying another lantern, tumbled into the stern; and, in the unreasoning excitement of the moment, called out “Mr. Helsingham, Mr. Helsingham! Hi, hi! Mr. Helsingham!” in a piping voice which sounded through the darkness like that of a lost soul.

The pandemonium upon the steamer was appalling. The jabbering native sailors ran aimlessly to and fro, flinging ropes and buoys into the river from the vessel’s stern; while the Egyptian captain, completely losing his head, rang and bawled orders down to the engine-room, as a result of which the paddle-wheels churned up the water, now this way, now that. Lady Smith-Evered and Mr. Bindane leant over the rail, shouting instructions to Professor Hyley as the boat dropped into the distance.
