"Do you know this boy?"

Tom saw the Arab's eyelids quiver.

"No--I do not know him, master. I never saw him before."

Major Burnaby turned to the Muhima.

"Mbutu, is this the man?" he asked.

"Him sure nuff, sah; him gib me kiboko."

"The boy lies. I never saw him; I know nothing about him."

"Very well. I shall have to refresh your memory. Fadl, tell Sergeant Abdullah to bring up a firing-party."

There was a strained silence. The Arab looked round apprehensively as six men of the King's African Rifles came up, ordered arms, and stood rigidly at attention.

The major took his watch from his pocket and laid it on the table in front of him.
