He brooded. The unfairness of Fate was souring him. A man expects trouble in his affairs of the heart from soldiers and sailors, and to be cut out by even a postman is to fall before a worthy foe; but milkmen—no! Only grocers' assistants and telegraph-boys were intended by Providence to fear milkmen.

Yet here was Alf Brooks, contrary to all rules, the established pet of the mansions. Bright eyes shone from balconies when his 'Milk—oo—oo' sounded. Golden voices giggled delightedly at his bellowed chaff. And Ellen Brown, whom he called Little Pansy-Face, was definitely in love with him.

They were keeping company. They were walking out. This crushing truth Edward Plimmer learned from Ellen herself.

She had slipped out to mail a letter at the pillar-box on the corner, and she reached it just as the policeman arrived there in the course of his patrol.

Nervousness impelled Constable Plimmer to be arch.

''Ullo, 'ullo, 'ullo,' he said. 'Posting love-letters?'

'What, me? This is to the Police Commissioner, telling him you're no good.'

'I'll give it to him. Him and me are taking supper tonight.'

Nature had never intended Constable Plimmer to be playful. He was at his worst when he rollicked. He snatched at the letter with what was meant to be a debonair gaiety, and only succeeded in looking like an angry gorilla. The girl uttered a startled squeak.

The letter was addressed to Mr A. Brooks.
