"Well, Mr. Durrant, all that you’ve just told me is extremely interesting. Will you wait a few moments?" and rising, he left the room. On his return five minutes later, he asked Gerald to accompany him. They went together down a long corridor, where the young man was ushered into a comfortable office. A well-dressed man of rather dapper appearance was seated at a table, and Gerald was invited to a chair, when he was closely questioned, more especially regarding his observations and those of Marigold upon the houses in Pont Street and Upper Brook Street, and also concerning the trap into which he himself had fallen, and Marigold’s inexplicable illness. "Is the young lady yet fit to see anyone, do you think?" asked the superintendent. "Is she well enough to make a statement?" "Not to-day, I fear. Perhaps she will be to-morrow." His interrogator reflected for a few moments. "When is that appointment due with Mr. Macdonald and the Frenchman—Galtier is his name, isn’t it?" he asked his secretary, who was seated at a table on the opposite side of the room. "They are due here now," was the latter’s reply as he glanced at the clock. "Mr. Emery is also to be here, is he not, Mr. Francis?" "Yes, sir," replied the secretary. Five minutes later there assembled in that room five other persons. Charles Emery was shown in with the inquisitive little man, Alexander Macdonald, who had arrived in Ardlui, and, giving his name as John Greig, had watched the Red Widow by orders from the detective office in Glasgow, and had gone back down Loch Lomond only half convinced that he was on the wrong track, and that she was not the notorious woman, Sarah Slade, for whom he was in search. Alexander Macdonald was, however, a very shrewd person, and when the first suspicion of a new case was aroused against Ena Pollen, as she now called herself, he saw that he had been sadly misled. Therefore, unknown to Scotland Yard, the Glasgow police had been doing underground work in order to fix the identity of the lady of Upper Brook Street. Almost simultaneously with the arrival of the two men there came Céline and Galtier, together with a well-dressed elderly man, the manager of the insurance company in which the false Mrs. Morrison had taken out a policy. For a full hour they sat with the superintendent of the Criminal Investigation Department, who, with a shorthand writer at his elbow, heard the further statement of each in turn. At last, turning to Inspector Shaw, he said: "There is certainly sufficient evidence to justify the immediate arrest of the two women and the man Boyne. We must get the statements of Miss Ramsay and her aunt later." Then, taking a sheet of pale-yellow official paper, he scribbled one or two lines, signed them, and handed it to Shaw.
