"But what does he do?" persisted the Saint.

"He is — ah — somewhat difficult to get on with," replied Mr. Potham cautiously.

More than that his discretion would not permit him to say; but the Saint's appetite was far from satisfied. In fact, Simon Templar was so intrigued with the unpopularity of Major Bellingford Smart that he took his leave of Mr. Potham rather abruptly, leaving that discreet gentleman gaping in some astonishment at a virginal pad of Orders to View on which he had not been given a chance to inscribe any addresses for the Saint's inspection.

Simon Templar was not actively in search of trouble at that time. His hours of meditation, as a matter of fact, were almost exclusively occupied with the problem of devising for himself an effective means of entering the town house of the Countess of Albury (widow of Albury's Peerless Pickles) whose display of diamonds at a recent public function had impressed him as being a potential contribution to his Old Age Pension that he could not conscientiously pass by. But one of those sudden impulses of his had decided that the time was ripe for knowing more about Major Bellingford Smart; and in such a mood as that, a comparatively straightforward proposition like the Countess of Albury's diamonds had to take second place.

Simon went along to a more modern real estate agency than the honourable firm of Potham & Spode, one of those marble-pillared, super-card-index billeting offices where human habitations are shot at you over the counter like sausages in a cafeteria; and there an exquisitely-dressed young man with a double-breasted waistcoat and impossibly patent-leather hair, who looked as if he could have been nothing less than the second son of a duke or an ex-motor-salesman, was more communicative than Mr. Potham had been. It is also worthy of note that the exquisite young man thought that he was volunteering the information quite spontaneously, as a matter of interest to an old friend of his youth; for the Saint's tact and guile could be positively Machiavellian when he chose.

"It's rather difficult to say exactly what is the matter with Bellingford Smart. He seems to be one of these sneaking swine who gets pleasure out of taking advantage of their position in petty ways. As far as his tenants are concerned, he keeps to the letter of his leases and makes himself as nasty as possible within those limits. There are lots of ways a landlord can make life unbearable for you if he wants to, as you probably know. The people he likes to get into his flats are lonely widows and elderly spinsters — they're easy meat for him."

"But I don't see what good that does him," said the Saint puzzledly. "He's only getting himself a bad name —"

"I had one of his late tenants in here the other day — she told me that she'd just paid him five hundred pounds to release her. She couldn't stand it any longer, and she couldn't get out any other way. If he does that often, I suppose it must pay him."

"But he's making it more and more difficult to let his flats, isn't he?"

The exquisite young man shrugged.
