Matthew regarded Alastair with dislike. Cordelia felt a familiar sinking of her heart. This was how it always went now, when Alastair interacted with any of the Merry Thieves. Suddenly, a few months ago, they had all become enormously angrier at Alastair, and she had no idea why. She couldn’t bring herself to ask. “James was called away on important business.”

“What business?” said Alastair.

“No business of yours,” Matthew said, clearly pleased with himself. “Rather walked into that one, eh?”

Alastair’s black eyes glittered. “You had best not lead my sister into trouble, Fairchild,” he said. “I know the kind of company you keep.”

“Alastair, stop it,” Cordelia said. “Now, are you really skipping out on the Pouncebys’ party or were you just needling Mother? And if the latter, do you wish to accompany Matthew and myself in the carriage?”

Alastair’s gaze flicked to Matthew. “Why,” he said, “are you not even wearing a hat?”

“And cover up this hair?” Matthew indicated his golden locks with a flourish. “Would you blot out the sun?”

Alastair wore the sort of expression that indicated that no amount of eye rolling would be enough. “I,” he said, “am going for a walk.”

He stalked out into the snowy night without another word, the effect of his exit dampened by the snow swallowing up the tread of his boots.

Cordelia sighed and started down the walk with Matthew. South Kensington was a fairy tale of white houses frosted in shimmering ice, the glow of the streetlamps shrouded in halos of snow-softened mist. “I feel I am ever apologizing for Alastair. Last week he made the milkman cry.”

Matthew handed her up to the carriage seat. “Never apologize for Alastair to me. He provides me an adversary to sharpen my wits on.”

He swung himself up next to her and closed the heavy door. The silk-lined interior of the carriage was made cozy by soft cushions and velvet curtains over the windows. Cordelia sat back against the bench, the sleeve of Matthew’s greatcoat brushing her arm reassuringly.

“I feel as if I haven’t seen you in an age, Matthew,” she said, happy to change the subject. “I heard your mother was back from Idris? And Charles from Paris?” As Consul, Matthew’s mother, Charlotte, was often away from London. Her son Charles, Matthew’s brother, had taken a junior position at the Paris Institute, where he was training in politics: everyone knew Charles hoped to be the next Consul someday.

Matthew ran his fingers through his hair, dislodging ice crystals. “You know Mother—the minute she steps from her carriage she’s off and running again. And of course Charles lost no time in coming home to see her. Reminding the Paris Institute of how close he is to the Consul, how much she depends on his advice. Pontificating to Father and Martin Wentworth. When I left, he had interrupted their chess match to try to drag them into a discussion of Downworlder politics in France. Wentworth was looking a bit desperate, actually—probably hoping Christopher would cause another explosion in the lab to give him an opportunity to escape.”
