"Every second was of value: instant action was the thing! Police headquarters was warned at once; and, but a few minutes had elapsed, when Monsieur Havard arrived in a taxicab to take charge of the investigations.
"Thanks to the courtesy of Monsieur Havard, we were allowed to accompany him to the stone-yards of the Metropolitan: the police were convinced that it was hereabouts that the robbery had been accomplished. We reached the spot about an hour after the explosion. The first investigations produced no result; but Monsieur Havard pursued his solitary search up one of the sidings, and had his reward. His exclamation was heard, and we hastened to the spot.... He had just found a second hand-cart, in all points similar to that he had recently examined in the courtyard of the Barbey-Nanteuil bank!
"Monsieur Havard at once realised that he had before his eyes the original hand-cart, and that the hand-cart he had seen in the bank courtyard was a clever substitute! It need scarcely be said that there is no trace of the stolen millions to be found in the original hand-cart, cast away in a siding of the Metropolitan....
"Our readers know something of the appearance presented by these lines, in course of construction on the Metropolitan railway. We have repeatedly published in La Capitale details regarding the way in which the engineers and workmen supervise and execute the cutting of the passageway on the underground. The operations in the place de l'Opéra are on an enormous scale, for there is a junction here, and the soil is more undermined than elsewhere on the railway.
"At the precise spot where the explosion occurred, there are four galleries in course of construction: one is the future Auteuil-Opéra line, the others either lead to existing lines, or are galleries made for the convenience of the workmen. Hand-cart number one, that is to say, the substituted hand-cart filled with sacks of lead, was found in the passageway of the Auteuil-Opéra line, which is perfectly accessible, and would naturally be visited by the rescuers.
"The original hand-cart was hidden away in one of the lateral galleries, which are small and narrow, and not likely to be visited and examined, except as a last resource. It is, therefore, clear that the affair has been carefully arranged: a premeditated robbery. The presence of the two hand-carts would establish this—the hand-carts used by the bank for the transport of bullion and other forms of money are of a particular make—unique, in fact. Their respective positions show that the robbers had carefully prepared their drama, and it was skilfully arranged.
"Thanks to Monsieur Havard's kindness, we were permitted to approach the original hand-cart. It was in a lamentable condition: the body of it was nearly smashed to pieces! Of course, no traces of the seals were to be found. The only remark we see fit to make in this connection is, that Monsieur Nanteuil, his clerks, and those who witnessed the accident, must have been greatly excited and upset, otherwise they would naturally have been much astonished at finding the substituted hand-cart practically uninjured after an accident of so crushing a nature.
"We have carefully examined the soil round the original hand-cart, in the hope of finding some clear footprints of the thieves, or their accomplices; but it was impossible to draw any conclusion from this examination—the footmarks are intermingled, superimposed, undistinguishable. It must be admitted the soil of the Metropolitan, hereabouts, has been very much trampled over and beaten down so that it is difficult to believe that researches, with the object of discovering the robbers' footmarks, are likely to have any clear result.
"At the moment these lines have been written, the investigation in the Metropolitan passageways still continues, and will, in all probability, be continued late into the night. So far, the police admit that results are meagre. Monsieur Havard considers it certain that the deed is a premeditated one, carefully prepared, and that, consequently, the explosion which caused the catastrophe was a deliberate act of violence. On the other hand, Monsieur Nanteuil declares that outside the parties interested, that is to say, the Barbey-Nanteuil bank and the Comptoir d'Escomptes, who were to receive the bullion, not a soul could know of the transfer on that particular morning. But the staffs of the bank and of the Comptoir National d'Escomptes are absolutely trustworthy: their honour has never been questioned.
"It is evident that such a daring and desperate deed, carried through so successfully in the galleries of the Metropolitan, in the sight of all Paris, at eleven o'clock in the morning, could only be the work of a band of criminals, numerous and perfectly organised.
