Confirmation of his suspicions was to come from London. The remains of the trunk found at Millery had been skilfully put together and exposed at the Morgue in Paris, whilst the Gouffe family had offered a reward of 500 francs to anybody who could in any way identify the trunk. Beyond producing a large crop of anonymous letters, in one of which the crime was attributed to General Boulanger, then in Jersey, these measures seemed likely to prove fruitless. But one day in December, from the keeper of a boarding-house in Gower Street, M. Goron received a letter informing him that the writer believed that Eyraud and Gabrielle Bompard had stayed recently at his house, and that on July 14 the woman, whom he knew only as "Gabrielle," had left for France, crossing by Newhaven and Dieppe, and taking with her a large and almost empty trunk, which she had purchased in London. Inquires made by the French detectives established the correctness of this correspondent's information. An assistant at a trunk shop in the Euston Road was able to identify the trunk--brought over from Paris for the purpose--as one purchased in his shop on July 12 by a Frenchman answering to the description of Michel Eyraud. The wife of the boarding-house keeper recollected having expressed to Gabrielle her surprise that she should buy such an enormous piece of luggage when she had only one dress to put into it. "Oh that's all right," answered Gabrielle smilingly, "we shall have plenty to fill it with in Paris!" Gabrielle had gone to Paris with the trunk on July 14, come back to London on the 17th, and on the 20th she and Eyraud returned together to Paris From these facts it seemed more than probable that these two were the assassins so eagerly sought for by the police, and it seemed clear also that the murder had been done in Paris. But what had become of this couple, in what street, in what house in Paris had the crime been committed? These were questions the police were powerless to answer.
