"You drove a party from Athelstan Road early this morning?"
"Yes."
I counted five shillings into the boy's outstretched hand, and he scampered away in great delight.
"There's half-a-sovereign for you," I said to Bill Foster, "if you answer correctly a few questions."
"About the party I drove from Athelstan Road?" he asked.
"My questions will refer to them. You seem to hesitate."
"The fact is," said Bill Foster, "the gentleman gave me a florin over my fare to keep my mouth shut."
"Only a fifth of what I offer you," I said.
"Make it a sovereign," suggested Devlin.
