Yes, there's no doubt that Muller is different, as the authors take great pains to inform us. What makes these worth reading, though, is the difference in old Austrian society from our own, more than Muller's detecting. While ingenious, the clues too often fall into Muller's hands, and his initial hypothesies are too often right on the money.
Over the past several months I've read numerous mysteries written from post US Civil War to the great Depression. Though some have been interesting, the majority have been unlikely, dependent upon coincidence or weakly written. Hand in the Dark is the best I've yet read.
It's lengthy but complex, covering a gruesome and puzzling murder that occurs in an English country home, and reviewing the individual reasonings of three competing detectives.

I'm no fan of Oppenheim. He uses language well but often plots poorly, has limited characters, and his premises are questionable. Illustrious Prince is the most preposterous story of his that I've yet read.
Puzzled by a complex murder--the victim having been electrocuted, poisoned, head-bashed and stabbed? And what of all the clocks being stopped at different times, eh? Fortunately the next murder is simpler, no electricity being involved.
Not to worry, for Colonel R E Lee Ashley, America's answer to Inspector Clouseau, is on the job, sneaking and eavesdropping everywhere in the hopes that the murderer will inadvertently confess. Poor fish!
