Chess Detective Work

Retrograde analysis involves looking into a chess game’s past, rather than its future. Here’s an example from Henry Ernest Dudeney (1917):

Dudeney retrograde analysis

“Strolling into one of the rooms of a London club, I noticed a position left by two players who had gone. This position is shown in the diagram. It is evident that White has checkmated Black. But how did he do it? That is the puzzle.”

The solution is unique. Can you find it?

Daniel McCartney

Daniel McCartney never needed a diary — he could remember every day of his life since age 9. On his death in 1887, the Cardington, Ohio, Independent published this account:

That the reader may more clearly understand what has just been written, I will give Mr. McCartney’s answer to a question of my own: ‘Wife and I were married on the 28th day of January, 1836; give the day of the week, the kind of weather, etc.?’ He gave answer in a few seconds. ‘You were married on Thursday, there was snow on the ground, good sleighing and not very cold; father and I were hauling hay; a sole came off the sled, we had to throw the hay off, put a new sole on the sled and load up again before we could go.’

The writer (whose name is not given) met McCartney again a dozen years later and asked the same question. McCartney gave the same details.

“Singular Expedient”

A strange story is that related in a paper on ‘English and Irish Juries,’ in All the Year Round. The president judge in the case, Sir James Dyce, chief justice of the Court of Common Pleas, astonished at the verdict of acquittal in so plain a case, sought an interview with the foreman, who, having previously obtained a promise of secrecy during his lifetime, confessed that he had killed the man in a struggle in self-defence, and said that he had caused himself to be placed on the jury in order to insure his acquittal.

Here’s a valentine written by Edgar Allan Poe in 1846. His sweetheart’s name is hidden in it — can you find it?

For her these lines are penned, whose luminous eyes,
Brightly expressive as the starts of Leda,
Shall find her own sweet name that, nestling, lies
Upon the page, enwrapped from every reader.
Search narrowly these words, which hold a treasure
Divine — a talisman, an amulet
That must be worn at heart. Search well the measure —
The words — the letters themselves. Do not forget
The smallest point, or you may lose your labor.
And yet there is in this no gordian knot
Which one might not undo without a sabre
If one could merely comprehend the plot.
Upon the open page on which are peering
Such sweet eyes now, there lies, I say, perdus,
A musical name oft uttered in the hearing
Of poets, by poets — for the name is a poet’s too.
In common sequence set, the letters lying,
Compose a sound delighting all to hear —
Ah, this you’d have no trouble in descrying
Were you not something, of a dunce, my dear —
And now I leave these riddles to their Seer.

March 15, 1761, Tregoney, in Cornwall. As some tinners were lately employed on a new mine, one of them accidentally struck his pick-axe on a stone. The earth being removed, a coffin was found. On removing the lid they discovered a skeleton of a man of gigantic size, which, on the admission of the air, mouldered into dust. One entire tooth remained whole, which was two inches and a half long, and thick in proportion. The length of the coffin was eleven feet three inches, and depth three feet nine inches.

Bridge to Nowhere

On Nov. 7, 1940, photographer Leonard Coatsworth was halfway across Washington’s Tacoma Narrows Bridge when he felt it move strangely:

“Just as I drove past the towers, the bridge began to sway violently from side to side. Before I realized it, the tilt became so violent that I lost control of the car. … I jammed on the brakes and got out, only to be thrown onto my face against the curb… Around me I could hear concrete cracking. … The car itself began to slide from side to side of the roadway.”

Gripping the curb, he crawled 500 yards back toward the toll plaza, turned and watched his car plunge into the Narrows. With it went his daughter’s dog, Tubby, who was too terrified to jump out.

The bridge had been competently designed, with supports by Golden Gate designer Leon Moisseiff, but no one had counted on its twisting and buckling in the wind.

A Nautical Mystery

On Jan. 31, 1921, the five-masted commercial schooner Carroll A. Deering was found aground in North Carolina. The ship’s log, navigation equipment and lifeboats were missing, as were the crew’s personal effects. She had last been sighted by a lightship at Cape Lookout, whose captain had spoken with a thin man with reddish hair and a foreign accent — decidedly not the Deering‘s captain. The lightship also noted that the crew seemed to be “milling around” on the Deering‘s foredeck, where they were usually not allowed.

But that’s all anyone knows, really. The crew’s disappearance remains unexplained to this day. Was it piracy? Mutiny? A commandeering by Russian communists? Without evidence, it remains a mystery.
