Ripping Time by Robert Asprin & Linda Evans

Early morning light, watery and weak, tried vainly to break through rainclouds as Lachley stepped off Greenwich pier from the waterman’s taxi he’d taken down from London. The clock of the world-famous Greenwich observatory struck eight chimes as Lachley rented a nag from a dockside livery stable and met James Stephen, as agreed. The unsuspecting Stephen greeted him warmly. “Dr. Lachley! Well met, old chap! I say, it’s rather a dismal morning, but we’ll put a good face on it, eh? Company makes the gloomiest day brighter, what?”

“Indeed,” Lachley nodded, giving the doomed tutor a cheery smile.

The scent of the River Thames drifted on the damp breeze, mingling with the green smell of swampy ground from Greenwich Marshes and the acrid, harsh smell of coal smoke, but Dr. John Lachley drew a deep, double-lungful and smiled again at the man who rode beside him, who had but a quarter of an hour to live.

Riding down the waterfront, past berths where old fashioned, sail-powered clipper ships and small, iron-hulled steamers creaked quietly at anchor, Lachley and Mr. Stephen turned their nags up King William Walk to reach Greenwich Park, then headed parallel to the river past the Queen’s House, built for Queen Anne of Denmark by James the First in 1615. Greenwich boasted none of London’s stink, smelling instead of fresh marshes and late-autumn hay and old money. Tudor monarchs had summered here and several had been born in Greenwich palaces. The Royal Naval College, once a Royal Hospital for Seamen, shared the little village on the outskirts of London with the Royal Observatory and the world-famous Greenwich Meridian, the zero line of oceanic navigation.
