“Damn this curst family nose!” said Ludovic. “It’ll ruin me yet.”

“That’s what I’m thinking,” agreed Bundy. “However, there’s no sense in dwelling on what can’t be helped. If you’re ready to start milling this ken we’d best start without wasting any more time. And if you keep in mind that though maybe there ain’t enough light for anyone to know you by, there’s enough to spare to make you a hem easy target for any cove as might be sitting inside the house with a gun, I dare say you’ll come off safe yet.”

“It’s odds there’s no one there at all,” returned Ludovic. “But you needn’t fear me: I’m taking no risks tonight.”

This remark seemed to tickle Bundy’s sense of humour. He went off without warning into a paroxysm of silent laughter, which made his eyes water and his whole frame shake like a jelly. Ludovic paid not the least heed to this seizure, but led the way to a wicket gate at the back of the house, which gave on to the park from the shrubbery.

Traversing the shrubbery they made their way round to the front of the house, taking care not to tread upon the gravel path. Under the tall casement windows there were flowerbeds, in which a few snowdrops thrust up their heads. Ludovic counted the windows, made up his mind which room must be the library, and indicated it to Bundy with a jerk of his head. Bundy stepped across the path on to the flower-bed, and laid his ear to the glass. He could detect no sound within the room, nor any light behind the drawn curtains, and after a few moments of intent listening he put down his muffled lantern and produced a serviceable knife from his pocket. While he worked on the window Ludovic stood beside him, on the look-out for a possible ambush in the garden. His hat cast a deep shadow over his face, but the moonlight caught the silver mountings on his pistol, and made them gleam. The garden was planted with too many trees and shrubs to make it possible for him to be sure that no one was in hiding there, but he could discover no movement in any of the shadows, and was more than ever inclined to discount his cousin Tristram’s forebodings.

A click behind him made him turn his head. Bundy jerked his thumb expressively at one of the windows, and shut his knife. Having forced back the latch he gently prised the window open with his finger-nails. It swung outwards with a slight groan of its hinges. Bundy picked up his lantern in his left hand, unveiled it, and with his right grasped a fold of the velvet curtain, and drew it aside. The muzzle of Ludovic’s gun almost rested on his shoulder, but there was no need for it. The lantern’s golden beam, travelling round the room, revealed no lurking danger. The room was empty, its chairs primly arranged, its grate laid with sticks ready to be kindled when the master should return.

Bundy took a second look round, and then whispered: “Will you go in?”

Ludovic nodded, slid the pistol back into his boot and swung a leg over the windowsill.

“Easy now!” Bundy muttered, helping him to hoist himself into the room. “Wait till I’m with you!”

Ludovic, alighting in the room, said under his breath: “Stay where you are: I’m not sure whether it’s this room I want, or another. Give me the lantern!”
