Sherlock Holmes in Jersey City

October 30, 2018

Sherlock Holmes;the International Exhibition , having been all over the US.and having visited Canada and Australia. will be very near NYC during the BSI Weekend. (Opens Nov 3-thru May 27)

The location is the Science Center in Jersey City. About half hour UBER ride from midtown Manhattan. This will cost about $50, and if you share with a few Sherlockians, is reasonable.
There is public transportation as well, explained on the Center’s website but it involves a few changes, which may be time consuming if you are in NY for only a few days.
Dan Stashower and I worked long hours on this with Geoffrey Curley and the Exhibition Development Group (they refer to them selves as “The Exhibitionists” Hope you visit and enjoy it.
Please help us spread the word around

Details below on link.

By E.J. Wagner

A few years ago I was asked to write a chapter for a Baker Street Irregulars anthology called “Trenches- The War Service of Sherlock Holmes”. My mandate was to explore the forensic background of the Holmes story “His Last Bow”.

As the tale involves espionage just before World War 1, I soon found myself immersed in massive tomes about ciphers, codes, hidden rooms, secret passages, and the beginnings of the British Secret Service.

Far from a highly developed operation, the Service started as an amazingly amateur affair, cobbled together with spit, wit and hope.

In August of 1914, as war rumbled closer, the British citizenry was gripped by the fear that their country harbored unknown and vast numbers of German sympathizers, whose purpose it was to spy for the Kaiser, and to weaken Britain from within.

This fear was laced with a vague contempt, as spying was considered not quite gentlemanly.(”His Last Bow” reflects this.)


But clearly, spying in opposition was what was needed, and so the Secret Intelligence Services was born.

The first director was Sir Mansfield Smith Cummimgs, a talented naval officer whose career at sea was cut short by a growing tendency to sea sickness. He was further limited by the wooden leg which replaced the one he lost in a road accident. These limitationsin no way affected  either his éclat or his   penchant for originality.

During interviews with prospective agent he would often,without

warning, seize a sharp paper opener and stab his false leg through his trousers. If the prospective operative flinched, Cummings would shake his head sadly, “Sorry old chap,” he would say, “you won’t do..”

It was on Cummings’s watch that the mysterious “Room 40” was established.

Spoken of in hushed tones, wrapped in secrecy, “Room 40 ” was simply the original meeting place of four members of British intelligence who were fluent in German and had a gamesmen’s  interest in code breaking. As the group grew larger, more rooms were added, but were included in the same sobriquet.

The history of code breaking and secret messages was long and complex, but rarely of practical use militarily. Before Marconi and Mors, communications were very slow, and sensitive information rarely reached the tacticians in time to influence the outcome of battle.

The German agents active in   World War 1 England were largely ineffective. They frequently  hid messages in fake commercial orders and invoices, but were careless enough to write an  order  for sardines out of season and cigars from shops which didn’t sell them.

SIS caught on soon enough, and working with Sir Basil Thomson of the Special Branch, twenty-two of the Kaiser’s spies were caught and executed.

Eager to keep his agents from similar disasters, Cummings became obsessed with developing an invisible ink which was easily available, cheap, and hard to detect.

Lemon juice, an early candidate, was rejected as the acid in it damaged the pen nibs. Vinegar met the same fate.

Then an interesting  thought  from Room 40-semen would work perfectly!

“Capitol!” chortled Cummings. “Every man his own stylus!”

Unfortunately, this too was a dead end. Semen when dried has a distinctive texture and scent-a fact commonly observed by laundresses but evidently  not  ever by military officers


The attempt, however,  has been  noted by historians.

Cummings signed off the experiment as he signed everything-with

a dramatic “C”

Thus further extending his influence  on espionage history by helping to inspire the creation of a certain Mr. Bond..

Memory Serves

“Memory Serves”

E.J. Wagner

One cold gray March day back in the 80’s, I made my usual trip to Manhattan to meet my pathologist cousin Teddy, to share lunch and discuss murder.

We were both late, having each walked past the restaurant, in spite of having met at the same spot for months.

He blames our mutual lack of directional sense on genetic inheritance -jovially reminding me that our grandparents were cousins.

(Our grandparents had died years before I was born, but Teddy, 27 years my senior, has happily shared details of their eccentricities)

“Cousins? Did matchmakers allow sort of thing?”

“Matchmakers had nothing to do with it. They arranged it themselves-a true love match. They remained a very romantic, demonstrative couple all their lives. The family would tease them. She never called him ‘Lev’ which was his name-it was always ‘Mein Lieb ’.”

Due to the age gap between us and the fact that he had spent years in France, India, China and Burma working for the OSS, I didn’t get to know Teddy until I was an adult.

When I needed information on autopsy techniques for a Museum presentation ay Stony Brook University, I phoned him. He invited me to the medical examiner’s office to observe.

I watched, fascinated, as this soft spoken, gently humorous man neatly sliced a human liver and dropped the bits into what seemed to be a take out food container.

Intrigued, I became a frequent visitor to the Office.

Over time, Teddy became my mentor.

During our lunches, he convinced me that with his help I could write a valuable book on the history of forensic science.

“And it’s important to do-“ he’d tell me “if we don’t learn from the mistakes of the past we’ll repeat them”.

So I was shaken when he leaned across the table that March day and said-

“about the book-we’ll have to find someone else to mentor you. I’ve developed some neurological issues-memory gaps- definitely getting worse. I’ll help as long as I can-here’s a reading list..

(I notice it’s an inch thick and single spaced)

He describes the sort of forensic specialist I need to work with-who sounds like a mash up of Albert Schweitzer, Sherlock Holmes, and a particularly well disposed Saint Bernard.

“I’ll give you my notes-you can serve as my memory” he finished.

Teddy had presented a perfectly succinct well organized plan.

Sure he was suffering a case of mistaken self diagnosis, I was trying to say this tactfully when he suddenly demanded ;

“Our grandparents-did you know they were cousins? First cousins? She used to call him… what did she call him? What was it? I can’t remember!!”

“She called Mein Lieb” I told him.
