“Such is the fact,” said Trent. “I am going to cut you out again, inspector. I owe you one for beating me over the Abinger case, you old fox. But if you really mean that you’re not inclined for the social amenities just now, let us leave compliments and talk business.” He stepped to the table, glanced through the papers arranged there in order, and then turned to the open roll-top desk. He looked into the drawers swiftly. “I see this has been cleared out. Well now, inspector, I suppose we play the game as before.” Trent had found himself on a number of occasions in the past thrown into the company of Inspector Murch, who stood high in the councils of the Criminal Investigation Department. He was a quiet, tactful, and very shrewd officer, a man of great courage, with a vivid history in connection with the more dangerous class of criminals. His humanity was as broad as his frame, which was large even for a policeman. Trent and he, through some obscure working of sympathy, had appreciated one another from the beginning, and had formed one of those curious friendships with which it was the younger man’s delight to adorn his experience. The inspector would talk more freely to him than to any one, under the rose, and they would discuss details and possibilities of every case, to their mutual enlightenment. There were necessarily rules and limits. It was understood between them that Trent made no journalistic use of any point that could only have come to him from an official source. Each of them, moreover, for the honour and prestige of the institution he represented, openly reserved the right to withhold from the other any discovery or inspiration that might come to him which he considered vital to the solution of the difficulty. Trent had insisted on carefully formulating these principles of what he called detective sportsmanship. Mr. Murch, who loved a contest, and who only stood to gain by his association with the keen intelligence of the other, entered very heartily into “the game”. In these strivings for the credit of the press and of the police, victory sometimes attended the experience and method of the officer, sometimes the quicker brain and livelier imagination of Trent, his gift of instinctively recognizing the significant through all disguises. The inspector then replied to Trent’s last words with cordial agreement. Leaning on either side of the French window, with the deep peace and hazy splendor of the summer landscape before them, they reviewed the case. Trent had taken out a thin notebook, and as they talked he began to make, with light, secure touches, a rough sketch plan of the room. It was a thing he did habitually on such occasions, and often quite idly, but now and then the habit had served him to good purpose.
