The House That Jack Built by Robert Asprin & Linda Evans

The driver let go a voluable flood of invective and cracked his carriage whip, urging his horses up onto the pavement to bypass the crush of carriages in the street. Pedestrians scattered, cursing, as Margo shoved her knife back into her boot sheath and flung herself down to the street, pelting toward the Carlton Club once more. She dodged carriage wheels and horses, gained the pavement, and slung herself around startled gentlemen strolling from club to club. She finally gained the Carlton and hurled herself at the doors—only to be snatched back by Fitzwilliam.

“Here, now, where d’you think you’re going? This is a gentleman’s club! Take yourself away, you filthy bootblack!” He dragged Margo by the back of her shirt collar and shoved her roughly to the pavement, where she landed in an undignified sprawl.

“Listen to me!” she shot back to her feet. “I have to get a critical message to Mr. Tanglewood and Mr. Cartwright! Send a message, yourself, if you won’t let me in! Tell them Kaederman shot Mr. Moore and he’s going to kill Mr. Cartwright! They’re in terrible danger—!”

“Take yourself off before I summon a constable, you little lunatic!”

Margo darted past, but Fitzwilliam was quick. He trapped her between his body and the wall, pinning her like a bug on display. He boxed her ears so soundly, Margo’s head rang and her eyes streamed. She swore in gutter langage, then bit his hand, flinging herself around him and running toward the now-unguarded door.

“Stop that boy! Stop him, I say!”

A group of startled gentlemen just leaving the club made a grab for her. She slithered past, cursing them, and dragged out her pistol—then someone seized her shoulder and spun her around and pain exploded through her head, sending her sprawling across the pavement like a ragdoll.
