Yet the incontestable fact remains, unsatisfactory and disquieting, that many murder mysteries have baffled all inquiry, and that the long list of undiscovered crimes is continually receiving mysterious additions. An erroneous impression, however, prevails that such failures are more common in Great Britain than elsewhere. No doubt the British police are greatly handicapped by the law's limitations, which in England always act in protecting the accused. But with all their advantages, the power to make arrests on suspicion, to interrogate the accused parties and force on self-incrimination, the Continental police meet with many rebuffs. Numbers of cases are "classed," as it is officially called in Paris--that is, pigeon-holed for ever and a day, lacking sufficient proofs for trial, and in some instances, indeed, there is no clue whatever. In every country, and in all times, past and present, there have been crimes that defied detection.
Feuerbach, in his record of criminal trials in Bavaria, tells, for example, of the unsolved murder mystery of one Rupprecht, a notorious usurer of Munich, who was killed in 1817 in the doorway of a public tavern not fifty yards from his own residence. Yet his murderer was never discovered. The tavern was called the "hell"; it was a place of evil resort, for Rupprecht, a mean, parsimonious old curmudgeon, was fond of low company and spent most of his nights here, swallowing beer and cracking jokes with his friends. One night the landlord, returning from his cellar, heard a voice in the street asking for Rupprecht, and, going up to the drinking saloon, conveyed the message. Rupprecht went down to see his visitor and never returned. Within a minute deep groans were heard as of a person in a fit or in extreme pain. All rushed downstairs and found the old man lying in a pool of blood just inside the front door. There was a gaping wound in his head, but he was not unconscious, and kept repeating, "Wicked rogue! wicked villain! the axe! the axe!"

The wound had been inflicted by some sharp instrument, possibly a sword or sabre, wielded by a powerful hand. The victim must have been taken unawares, when his back was turned. The theory constructed by the police was that the murderer had waited within the porch out of sight, standing on a stone bench in a dark corner near the street door; that Rupprecht, finding no one to explain the summons, had looked out into the street and then had made to go back into the house. After he had turned the blow was struck. Thus not a scrap of a clue was left on the theatre of the crime. But Rupprecht was still alive and able to answer simple questions. A judge was summoned to interrogate him, and asked, "Who struck you?" "Schmidt," replied Rupprecht. "Which Schmidt?" "Schmidt the woodcutter." Further inquiries elicited statements that Schmidt had used a hatchet, that he lived in the Most, that they had quarrelled some time before. Rupprecht said he had recognised his assailant, and he went on muttering, "Schmidt, Schmidt, woodcutter, axe." To find Schmidt was naturally the first business of the police. The name was as common as Smith is with us, and many Schmidts were woodcutters. Three Schmidts were suspected. One was a known confederate of thieves; another had been intimate, but afterwards was on bad terms, with Rupprecht: this was "Big Schmidt"; the third, his brother, "Little Schmidt," also knew Rupprecht. All three, although none lived in the Most, were arrested and confronted with Rupprecht, but he recognised none of them; and he died next day, having become speechless and unconscious at the last. Only the first Schmidt seemed guilty; he was much agitated when interrogated, he contradicted himself, and could give no good account of the employment of his time when the offence was committed. Moreover, he had a hatchet; it was examined and spots were found upon it, undoubtedly of blood. He was brought into the presence of the dead Rupprecht, and was greatly overcome with terror and agitation.
