The taxi pulled up and stood panting.

"Shares, please!" said Nan, when he had paid the driver.

For an instant a look of swift negation flashed across Mallory's face, then he replied composedly:

"Your share is two shillings."

Nan tendered a two-shilling piece, blessing him in her heart for refraining from putting her under a financial obligation to a stranger. He accepted the money quite simply, and turning away to speak to a porter, he tucked the two-shilling piece into his waistcoat pocket, while an odd, contemplative little smile curved his lips.

There was some slight confusion in the mind of the porter, who exhibited a zealous disposition to regard the arrivals as one party and to secure them seats in the same compartment.

Mallory, unheard by Nan, enlightened him quietly.

"I see, sir. You want a smoker?"

Mallory nodded and tipped him recklessly.

"That's it. You find the lady a comfortable corner seat. I'll look after myself."
