"We have already spoken of the history, so far as it is known, of some of the places round us--'Castra Regis,' 'Diana's Grove,' and 'The Lair of the White Worm.' I would like to ask if there is anything not necessarily of evil import about any of the places?""Which?" asked Sir Nathaniel shrewdly.

"Well, for instance, this house and Mercy Farm?""Here we turn," said Sir Nathaniel, "to the other side, the light side of things. Let us take Mercy Farm first. When Augustine was sent by Pope Gregory to Christianise England, in the time of the Romans, he was received and protected by Ethelbert, King of Kent, whose wife, daughter of Charibert, King of Paris, was a Christian, and did much for Augustine. She founded a nunnery in memory of Columba, which was named SEDES MISERICORDIOE, the House of Mercy, and, as the region was Mercian, the two names became involved. As Columba is the Latin for dove, the dove became a sort of signification of the nunnery. She seized on the idea and made the newly-founded nunnery a house of doves. Someone sent her a freshly-discovered dove, a sort of carrier, but which had in the white feathers of its head and neck the form of a religious cowl. The nunnery flourished for more than a century, when, in the time of Penda, who was the reactionary of heathendom, it fell into decay.

In the meantime the doves, protected by religious feeling, had increased mightily, and were known in all Catholic communities.

When King Offa ruled in Mercia, about a hundred and fifty years later, he restored Christianity, and under its protection the nunnery of St. Columba was restored and its doves flourished again.

In process of time this religious house again fell into desuetude;but before it disappeared it had achieved a great name for good works, and in especial for the piety of its members. If deeds and prayers and hopes and earnest thinking leave anywhere any moral effect, Mercy Farm and all around it have almost the right to be considered holy ground.""Thank you, sir," said Adam earnestly, and was silent. Sir Nathaniel understood.

After lunch that day, Adam casually asked Sir Nathaniel to come for a walk with him. The keen-witted old diplomatist guessed that there must be some motive behind the suggestion, and he at once agreed.

As soon as they were free from observation, Adam began.

"I am afraid, sir, that there is more going on in this neighbourhood than most people imagine. I was out this morning, and on the edge of the small wood, I came upon the body of a child by the roadside.

At first, I thought she was dead, and while examining her, I noticed on her neck some marks that looked like those of teeth.""Some wild dog, perhaps?" put in Sir Nathaniel.
