This is an amalgamation of three volumes that Sobol published starting in 1969, the final one coming out in 1975. Readers may know him better for his Encyclopedia Brown series which was extensive and which ran from 1963 to 2012. I've never read any of those, and I'm disinclined to do so after reading these stories, which are short, but rather violent, and often so simplistic, or so arcane, or so out of date that they're really not very entertaining. The book contains some 200 of them and my understanding is that many of these were actually in the Encyclopedia Brown series originally.
Each story covers only two pages in print, with the solution to the mystery printed (for reasons which escape me) upside down at the bottom of the second page. All of them are solved by Doctor Haledjian who hands-down beats Hermione Granger for being an insufferable know-it-all. He's obnoxious, and no one person could know all that he supposedly knows about every little thing. Worse than this though is that he's in every story, and nearly all of them are murders and robberies, which makes me highly-suspicious. How come so many serious crimes occur around Haledjian?! LOL!
The mysteries are of the nature of, for example, a guy supposedly entering a house from a freezing outdoors and claiming he saw a thief, and Haledjian calling him a liar on the basis that the guy's eyeglasses would have misted up as soon as he entered the warm house, and therefore he would have seen nothing. I'm serious, that's what they're like - all of them, except, for example, the ones which require you to know in detail how the old Pullman rail sleeping cars are organized, and so on.
Another example is where this guy wants to impress a girl so he hires a professional boxer to come on to the girl and then 'knocks him out' to impress her. The girl sees through this because the guy's eyeglasses, which he placed in his coat top pocket prior to fighting, survived the encounter unbroken despite the prize fighter delivering several body blows. The idea is that the eyeglasses must have broken, but that's not necessarily true. Even if they were hit, they might have survived and there was a relatively low chance that they'd be hit anyway, since a boxer would be punching to the abdomen and solar plexus rather than high on the chest. Despite that, this girl, who is all starry-eyed after the fight, suddenly rejects the guy (as she rightly should, it must be said) not because of the improbability of this wimpy guy surviving an assault from a prize fighter and then knocking him out cold with one punch, but solely on the basis of the eyeglasses being intact!
Another case of trapping a criminal hinges on the confusion between Anchorage - the port city in Alaska which contains almost half the state's population - and anchorage: that state of a ship being anchored somewhere, but Haledjian's persistent mistake is his flawed assumption that everyone knows the correct terminology for everything and routinely uses it in everyday interactions. He idiotically believes that everyone has his own knowledge pool, but had I heard this same thing, I would have assume Anchorage, Alaska was being referred to because most people don't say 'at anchorage', they say 'docked' even if that term is not strictly accurate! Again, for me it was really weak, and such a case would have been thrown out of court were there no other corroborative evidence.
In another case, Haledjian's idiotic incriminating evidence is that no railroad man would have said "twenty minutes after three," but instead would have said, "three-twenty," which is patent bullshit. His second line of devastating evidence is that no resident of San Francisco would ever call it 'Frisco. Again, had this case been tried on the basis of those two lines of 'evidence' it would have been summarily dismissed.
Another case hinges on a guy - who is dying of a stab wound - coming out of the house and telling Haledjian "Water" which shortly convinces him that this guy Scott is the guilty party. His 'reasoning' is that he learned from Scott that this guy was left-handed and consequently had all of his faucets switched so that the hot and cold water come out of the 'wrong' faucets as compared with the standard arrangement. Let's ignore the fact that this person being left-handed offers no rationale for switching faucets and put it down to the guy's eccentricity. What convinces Haledjian of Scott's guilt is that when he rushes into the house to get water (instead of immediately calling for an ambulance) he gets hot water rather than the cold he expected.
Haledjian realizes that Scott must have run the hot water to wash blood off his hands and this is why hot water came out immediately rather than taking time to warm up, and that therefore Scott is the murderer! If that's the case, why didn't the victim say "Scott stabbed me!" instead of offering the asinine cryptic clue 'water' and hoping Haledjian would make the labyrinthine connection? It's horseshit of the same stinking hue that Dan Brown created in the idiotic The Da Vinci Code when he had a dying man running around creating cryptic clues when he could simply have left a note explaining that a mad monk killed him, and asking in the note for Robert Langdon to contact his granddaughter!
So while I thought these would be entertaining, they were overall more annoying than anything. Once in a while there was an interesting or an entertaining one, but those were too few and far between for me to find this a commendable read. Maybe it would make a good bathroom book - you can always use the pages if you run out of toilet tissue! But as for me, I DNF'd it.
