Z 9 and Z 23 retired a few paces and conferred. A moment later they were fading discreetly away in the twilight.

Mame was left mistress of the field. But the incident rankled. Why could not a peaceful American citizeness enjoy the beauty of the evening and develop her personality without being shoved around in this way?

She heard the clocks of the neighbourhood chime six. And then, still ruffled, she left her seat and slowly made her way across the park towards bus Route 29. Alas! she had not gone far when she overtook a couple of elegant tunics. They were strolling twenty yards or so ahead, but even at this distance they were familiar.

On the inspiration of the moment she quickened her pace. Hearing a scrunch of footsteps on the gravel path, one of the cops half turned to look at her as she came up.

“Say, officer!” Mame’s gasp was all excitement: she would have known that sandy-haired, sharp-nosed rube among ten thousand of his kind. “Say, listen, officer!” An imperative hand was laid on an immaculate sleeve. “I seena mutt without his jeans.”

The words were intended to convey an impression of rusticity which, if anything, was overdone. Both bobbies turned as one towards her. Upon their faces was incomprehension grave and dour.

For the credit of the Metropolitan Force, however, the Second Cop was a young man of ripe experience. In fact, he was wearing the Zeebrugge Medal. At the end of 1919 he had been paid off from the Navy, after a brief but honourable career; in the spring of 1921 he had first donned the elegant tunic with belt and whistle complete whose accomplished wearers are the admiration of the world. There was a hiatus of sixteen months in his record which had been filled by slinging hash in a Chicago eating joint. Just as soon as he was able to hitch back his mind to that glad time, and with Mame’s intonation to help him, the process took rather less than thirty seconds, he knew where he was.

Emotion flamed suddenly in the eye of the Second Cop. He turned to the First Cop and spoke urgent words. Both zealots squared their shoulders and tightened their belts.

“Whaur did ye see him?” The demand of Z 9 was tense and stern.

Mame laid a finger to her lip. “Mind you don’t scare the guy.”
