Sarde was just ahead, riding abreast of the column in full view, but Chambers did not know his enemy by sight, and Buckie had not told.

"You see that officer?" I asked.

"Your partner," said the cowboy, "says that's Inspector Brown."

"Yes, Bunty Brown," said I.

"Your partner called him Jocko," said the cowboy. "So that's Sarde!" He whipped out his gun and spurred forward.

"Old Bunt was a jockey," I explained, "before he went to the bad and joined the police."

Chambers fell back beside me and sheathed his gun.

"Seen Mrs. Sarde?" I asked, to change the subject.

"Sent her a note," said Chambers; "she sent a letter back."

He would not tell me what was in that letter.
