Instantly his mind was made up. The guileless George Merrowdene hardly realized how it came about that he and the ex-inspector were strolling down the village together, and still less could he have said how it came about that the conversation should come round to the subject of life insurance.

Evans had no difficulty in attaining his object. Merrowdene of his own accord volunteered the information that he had just insured his life for his wife’s benefit, and asked Evans’s opinion of the company in question.

“I made some rather unwise investments,” he explained. “As a result my income has diminished. If anything were to happen to me, my wife would be left very badly off. This insurance will put things right.”

“She didn’t object to the idea?” inquired Evans casually. “Some ladies do, you know. Feel it’s unlucky—that sort of thing.”

“Oh, Margaret is very practical,” said Merrowdene, smiling. “Not at all superstitious. In fact, I believe it was her idea originally. She didn’t like my being so worried.”

Evans had got the information he wanted. He left the other shortly afterwards, and his lips were set in a grim line. The late Mr. Anthony had insured his life in his wife’s favour a few weeks before his death.

Accustomed to rely on his instincts, he was perfectly sure in his own mind. But how to act was another matter. He wanted, not to arrest a criminal red-handed, but to prevent a crime being committed, and that was a very different and a very much more difficult thing.

All day he was very thoughtful. There was a Primrose League Fête that afternoon held in the grounds of the local squire, and he went to it, indulging in the penny dip, guessing the weight of a pig, and shying at coconuts all with the same look of abstracted concentration on his face. He even indulged in half a crown’s worth of Zara, the Crystal Gazer, smiling a little to himself as he did so, remembering his own activities against fortune-tellers in his official days.

He did not pay very much heed to her singsong droning voice—till the end of a sentence held his attention.

“. . . And you will very shortly—very shortly indeed—be engaged on a matter of life or death . . . Life or death to one person.”

“Eh—what’s that?” he asked abruptly.

“A decision—you have a decision to make. You must be very careful—very, very careful . . . If you were to make a mistake—the smallest mistake—”

“Yes?”

The fortune-teller shivered. Inspector Evans knew it was all nonsense, but he was nevertheless impressed.

“I warn you—you must not make a mistake. If you do, I see the result clearly—a death. . . .”

Odd, damned odd. A death. Fancy her lighting upon that!

“If I make a mistake a death will result? Is that it?”

“Yes.”
