At the sight of a stranger the girl had paused, then, as if realising her tear-stained face and disordered hair, she turned and disappeared through the door from which she had rushed.

"My daughter," murmured the vicar, a little sadly, Malcolm Sage thought. "She has always been very highly strung and emotional," he added, as if considering some explanation necessary. "We have to be very stern with her on such occasions. It is the only way to repress it."

"You find it answers?" remarked Malcolm Sage.

"She has been much better lately, although she has been sorely tried.

Perhaps you have heard."

Malcolm Sage nodded absently, as he gazed intently at the thumb-nail of his right hand. A minute later he was walking down the drive, his thoughts occupied with the pretty daughter of the vicar of Gylston.

At the curate's lodgings he was told that Mr. Blade was away, and would not return until late that night.

As he turned from the gate, Malcolm Sage encountered a pale-faced, narrow-shouldered man with a dark moustache and a hard, peevish mouth.

To Malcolm Sage's question as to which was the way to the inn, he nodded in the direction from which he had come and continued on his way.

"A man who has failed in what he set out to accomplish," was Malcolm Sage's mental diagnosis of John Gray, the Gylston schoolmaster.

It was not long before Malcolm Sage realised that the village of Gylston was intensely proud of itself. It had seen in the London papers accounts of the mysterious scandal of which it was the centre.

A Scotland Yard officer had been down, and had subjected many of the inhabitants to a careful cross-examination. In consequence Gylston realised that it was a village to be reckoned with.

The Tired Traveller was the centre of all rumour and gossip. Here each night in the public-bar, or in the private-parlour, according to their social status, the inhabitants would forgather and discuss the problem of the mysterious letters. Every sort of theory was advanced, and every sort of explanation offered. Whilst popular opinion tended to the view that the curate was the guilty party, there were some who darkly shook their heads and muttered, "We shall see."

It was remembered and discussed with relish that John Gray, the schoolmaster, had for some time past shown a marked admiration for the vicar's daughter. She, however, had made it clear that the cadaverous, saturnine pedagogue possessed for her no attractions.

During the half-hour that Malcolm Sage spent at The Tired Traveller, eating a hurried meal, he heard all there was to be heard about local opinion.

The landlord, a rubicund old fellow whose baldness extended to his eyelids, was bursting with information. By nature capable of making a mystery out of a sunbeam, he revelled in the scandal that hummed around him.

After a quarter of an hour's conversation, the landlord's conversation, Malcolm Sage found himself possessed of a bewildering amount of new material.

"A young gal don't have them highsterics for nothin'," my host remarked darkly. "Has fits of 'em every now and then ever since she was a flapper, sobbin' and cryin' fit to break 'er heart, and the vicar that cross with her."

"That is considered the best way to treat hysterical people,"

remarked Malcolm Sage.

"Maybe," was the reply, "but she's only a gal, and a pretty one too," he added inconsequently.

"Then there's the schoolmaster," he continued, "'ates the curate like poison, he does. Shouldn't be surprised if it was him that done it. 'E's always been a bit sweet in that quarter himself, has Mr.

Gray. Got talked about a good deal one time, 'angin' about arter Miss Muriel," added the loquacious publican.

By the time Malcolm Sage had finished his meal, the landlord was well in his stride of scandalous reminiscence. It was with obvious reluctance that he allowed so admirable a listener to depart, and it was with manifest regret that he watched Malcolm Sage's car disappear round the curve in the road.

A little way beyond the vicarage, an admonitory triangle caused Tims to slow up. Just by the bend Malcolm Sage observed a youth and a girl standing in the recess of a gate giving access to a meadow.

Although they were in the shadow cast by the hedge, Malcolm Sage's quick eyes recognised in the girl the vicar's daughter. The youth looked as if he might be one of the lads of the village.

In the short s.p.a.ce of two or three seconds Malcolm Sage noticed the change in the girl. Although he could not see her face very clearly, the vivacity of her bearing and the ready laugh were suggestive of a gaiety contrasting strangely with the tragic figure he had seen in the afternoon.

Muriel Crayne was obviously of a very mercurial temperament, he decided, as the car swung round the bend.

The next morning, in response to a telephone message, Inspector Murdy called on Malcolm Sage.

"Well, Mr. Sage," he cried, as he shook hands, "going to have another try to teach us our job," and his blue eyes twinkled good-humouredly.

The inspector had already made up his mind. He was a man with many successes to his record, achieved as a result of undoubted astuteness in connection with the grosser crimes, such as train-murders, post-office hold-ups and burglaries. He was incapable, however, of realising that there existed a subtler form of law-breaking, arising from something more intimately a.s.sociated with the psychic than the material plane.

"Did you see Mr. Blade?" enquired Malcolm Sage.

"Saw the whole blessed lot," was the cheery reply. "It's all as clear as milk," and he laughed.

"What did Mr. Blade say?" enquired Malcolm Sage, looking keenly across at the inspector.

"Just that he had nothing to say."

"His exact words. Can you remember them?" queried Malcolm Sage.

"Oh, yes!" replied the inspector. "He said, 'Inspector Murdy, I have nothing to say,' and then he shut up like a real Whitstable."

"He was away yesterday," remarked Malcolm Sage, who then told the inspector of his visit. "How about John Gray, the schoolmaster?" he queried.

"He practically told me to go to the devil," was the genial reply.

Inspector Murdy was accustomed to rudeness; his profession invited it, and to his rough-and-ready form of reasoning, rudeness meant innocence; politeness guilt.

He handed to Malcolm Sage a copy of a list of people who purchased "Olympic Script" from Mr. Grainger, the local Whiteley, volunteering the information that the curate was the biggest consumer, as if that settled the question of his guilt.

"And yet the vicar would not hear of the arrest of Blade," murmured Malcolm Sage, turning the copper ash-tray round with his restless fingers.

The inspector shrugged his ma.s.sive shoulders.

"Sheer good nature and kindliness, Mr. Sage," he said. "He's as gentle as a woman."

"I once knew a man," remarked Malcolm Sage, "who said that in the annals of crime lay the master-key to the world's mysteries, past, present and to come."

"A dreamer, Mr. Sage," smiled the inspector. "We haven't time for dreaming at the Yard," he added good-temperedly, as he rose and shook himself like a Newfoundland dog.

"I suppose it never struck you to look elsewhere than at the curate's lodgings for the writer of the letters?" enquired Malcolm Sage quietly.

"It never strikes me to look about for someone when I'm sitting on his chest," laughed Inspector Murdy.

"True," said Malcolm Sage. "By the way," he continued, without looking up, "in future can you let me see every letter as it is received? You might also keep careful record of how they are delivered."

"Certainly, Mr. Sage. Anything that will make you happy."

"Later I may get you to ask the vicar to seal up any subsequent anonymous letters that reach him without allowing anyone to see the contents. Do you think he would do that?"

"Without doubt if I ask him," said the inspector, surprise in his eyes as he looked down upon the cone of baldness beneath him, realising what a handicap it is to talk to a man who keeps his eyes averted.

"He must then put the letters in a place where no one can possibly obtain access to them. One thing more," continued Malcolm Sage, "will you ask Miss Crayne to write out the full story of the letters as far as she personally is acquainted with it?"
