From these impressions Watson, in his own workshop, would make the duplicate keys and file them away for future use. To each key he would attach a tag bearing the address of the building and a little diagram showing the exact location of the door which the key unlocked.
"Dutch Dan's" active part in the proposed crime ended as soon as the keys were made. Then, from the wide circle of criminals that he knew, he would select a number of expert burglars and hand them a set of the keys and diagrams, showing just how the robbery was to be carried out.
If the burglars were successful they turned over to "Dutch Dan" 20 per cent. of the proceeds. This mode of operation proved very profitable for Watson, and I remember that he often had as many as eight different parties of burglars working for him at one time.
And Watson, like Einstein, was sent to his grave by a fellow criminal, who had been discarded from his gang and killed him in revenge.
Will any reader who has reviewed with me the lives of the famous criminals recounted above dispute my assertion that, truly, CRIME DOES NOT PAY?
