"The operative had a hunch that it was a summons to another case and he was dog tired. But the boy kept singing out the name through the train and finally landed his man, thus being indirectly responsible for the solution of a mystery that might have remained unsolved for weeks--and incidentally saved the government nearly every cent of the one hundred and thirty thousand dollars."
When Drummond opened the telegram [continued Quinn] he found that it was a summons to Philadelphia, signed by Hamlin, a.s.sistant Secretary of the Treasury.
"Preston needs you at once. Extremely important," read the wire--and, as Drummond was fully aware that Preston was Director of the United States Mint, it didn"t take much deduction to figure that something had gone wrong in the big building on Spring Garden Street where a large part of the country"s money is coined.
But even the lure of the chase--something you read a lot about in detective stories, but find too seldom in the real hard work of tracing criminals--did not offset Drummond"s disappointment in having to defer his vacation. Grumbling, he gathered his bags and cut across New York to the Pennsylvania Station, where he was fortunate enough to be able to make a train on the point of leaving for Philadelphia. At the Mint he found Director Preston and Superintendent Bosbysh.e.l.l awaiting him.
"Mr. Hamlin wired that he had instructed you to come up at once," said the director. "But we had hardly hoped that you could make it so soon."
"Wire reached me on board a train that would have pulled out of Grand Central Station in another three minutes," growled Drummond. "I was on my way to Maine to forget all about work for a month. But," and his face broke into a smile, "since they did find me, what"s the trouble?"
"Trouble enough," replied the director. "Some hundred and thirty thousand dollars in gold is missing from the Mint!"
"What!" Even Drummond was shaken out of his professional calm, not to mention his grouch. Robbery of the United States Treasury or one of the government Mints was a favorite dream with criminals, but--save for the memorable occasion when a gang was found trying to tunnel under Fifteenth Street in Washington--there had been no time when the scheme was more than visionary.
"Are you certain? Isn"t there any chance for a mistake?"
The questions were perfunctory, rather than hopeful.
"Unfortunately, not the least," continued Preston. "Somebody has made away with a hundred and thirty thousand dollars worth of the government"s money. Seven hundred pounds of gold is missing and there isn"t a trace to show how or where it went. The vault doors haven"t been tampered with. The combination of the grille inside the vault is intact.
Everything, apparently, is as it should be--but fifty bars of gold are missing."
"And each bar," mused Drummond, "weighs--"
"Fourteen pounds," cut in the superintendent.
Drummond looked at him in surprise.
"I beg your pardon," said Preston. "This is Mr. Bosbysh.e.l.l, superintendent of the Mint. This thing has gotten on my nerves so that I didn"t have the common decency to introduce you. Mr. Bosbysh.e.l.l was with me when we discovered that the gold was missing."
"When was that?"
"Yesterday afternoon," replied the director. "Every now and then--at irregular intervals--we weigh all the gold in the Mint, to make sure that everything is as it should be. Nothing wrong was discovered until we reached Vault Six, but there fifty bars were missing. There wasn"t any chance of error. The records showed precisely how much should have been there and the scales showed how much there was, to the fraction of an ounce.
"But even if we had only counted the bars, instead of weighing each one separately, the theft would have been instantly discovered, for the vault contained exactly fifty bars less than it should have. It was then that I wired Washington and asked for a.s.sistance from the Secret Service."
"Thus spoiling my vacation," muttered Drummond. "How many men know the combination to the vault door?"
"Only two," replied the superintendent. "Cochrane, who is the official weigher, and myself. Cochrane is above suspicion. He"s been here for the past thirty years and there hasn"t been a single complaint against him in all that time."
Drummond looked as if he would like to ask Preston if the same could be said for the superintendent, but he contented himself with listening as Bosbysh.e.l.l continued:
"But even if Cochrane or I--yes, I"m just as much to be suspected as he--could have managed to open the vault door unseen, we could not have gotten inside the iron grille which guards the gold in the interior of the vault. That is always kept locked, with a combination known to two other men only. There"s too much gold in each one of these vaults to take any chance with, which is the reason for this double protection.
Two men--Cochrane and I--handle the combination to the vault door and open it whenever necessary. Two others--Jamison and Strubel--are the only ones that know how to open the grille door. One of them has to be present whenever the bars are put in or taken away, for the men who can get inside the vault cannot enter the grille, and the men who can manipulate the grille door can"t get into the vault."
"It certainly sounds like a burglar-proof combination," commented Drummond. "Is there any possibility for conspiracy between"--and he hesitated for the fraction of a second--"between Cochrane and either of the men who can open the grille door?"
"Apparently not the least in the world," replied Preston. "So far as we know they are all as honest as the day--"
"But the fact remains," Drummond interrupted, "that the gold is missing."
"Exactly--but the grille door was sealed with the official governmental stamp when we entered the vault yesterday. That stamp is applied only in the presence of both men who know the combination. So the conspiracy, if there be any, must have included Cochrane, Strubel, and Jamison--instead of being a two-man job."
"How much gold did you say was missing?" inquired the Treasury operative, taking another tack.
"Seven hundred pounds--fifty bars of fourteen pounds each," answered Bosbysh.e.l.l. "That"s another problem that defies explanation. How could one man carry away all that gold without being seen? He"d need a dray to cart it off, and we"re very careful about what goes out of the Mint.
There"s a guard at the front door all the time, and no one is allowed to leave with a package of any kind until it has been examined and pa.s.sed."
A grunt was Drummond"s only comment--and those who knew the Secret Service man best would have interpreted the sound to mean studious digestion of facts, rather than admission of even temporary defeat.
It was one of the government detective"s pet theories that every crime, no matter how puzzling, could be solved by application of common-sense principles and the rules of logic. "The criminal with brains," he was fond of saying, "will deliberately try to throw you off the scent. Then you"ve got to take your time and separate the wheat from the chaff--the false leads from the true. But the man who commits a crime on the spur of the moment--or who flatters himself that he hasn"t left a single clue behind--is the one who"s easy to catch. The cleverest crook in the world can"t enter a room without leaving his visiting card in some way or other. It"s up to you to find that card and read the name on it. And common sense is the best reading gla.s.s."
Requesting that his mission be kept secret, Drummond said that he would like to examine Vault No. Six.
"Let Cochrane open the vault for me and then have Jamison and Strubel open the grille," he directed.
"Unless Mr. Bosbysh.e.l.l opened the vault door," Preston reminded him, "there"s no one but Cochrane who could do it. It won"t be necessary, however, to have either of the others open the grille--the door was taken from its hinges this morning in order the better to examine the place and it hasn"t yet been replaced."
"All right," agreed Drummond. "Let"s have Cochrane work the outer combination, then. I"ll have a look at the other two later."
Accompanied by the director and the superintendent, Drummond made his way to the bas.e.m.e.nt where they were joined by the official weigher, a man well over fifty, who was introduced by Preston to "Mr. Drummond, a visitor who is desirous of seeing the vaults."
"I understand that you are the only man who can open them," said the detective. "Suppose we look into this one," as he stopped, as if by accident, before Vault No. 6.
Cochrane, without a word, bent forward and commenced to twirl the combination. A few spins to the right, a few to the left, back to the right, to the left once more--and he pulled at the heavy door expectantly. But it failed to budge.
Again he bent over the combination, spinning it rapidly. Still the door refused to open.
"I"m afraid I"ll have to ask you to help me with this, Superintendent,"
Cochrane said, finally. "It doesn"t seem to work, somehow."
But, under Bosbysh.e.l.l"s manipulation, the door swung back almost instantly.
"Nothing wrong with the combination," commented Preston.
Drummond smiled. "Has the combination been changed recently?" he asked.
"Not for the past month," Bosbysh.e.l.l replied. "We usually switch all of them six times a year, just as a general precaution--but this has been the same for the past few weeks. Ever since the fifteenth of last month, to be precise."
Inside the vault Drummond found that, as Preston had stated, the door to the grille had been taken from its hinges, to facilitate the work of the men who had weighed the gold, and had not been replaced.
"Where are the gold bars?" asked the detective. "The place looks like it had been well looted."
"They were all taken out this morning, to be carefully weighed," was Preston"s reply.
"I"d like to see some of them stacked up there along the side of the grille, if it isn"t too much trouble."
