Dear Sir John
I was wondering as I was writing this whether “Dear Sir John” was the correct way to start the letter. Unfortunately, I couldn’t ascertain this because the local library is only open during daylight hours and my friend has been out of town for some time. At least that is what his butler informs me.
I was of a mind to deliver the device to you personally, but when Miss Henderson came to visit me with your instructions, she was very clear on the dangers. I do hope that the cloud of poisonous gas that has encircled your holiday resort clears shortly so that you may leave the town and indeed to allow visitors to approach it as well. Perhaps you could let me know exactly where you are, as Miss Henderson had a coughing fit whenever she said the name and I couldn’t be certain of what she said. I do hope she isn’t sickening for something. The same problem seemed to occur when she came back to pick up the device and this letter. I suggested a machine of my own invention that might help her, but she seemed a little startled when I suggested getting a closer look at her throat.
Anyway, I digress, I received the instructions in the telegrams and worked on the device as you asked. It might have been useful to show you exactly how to use it, but I will have to describe it here. I must admit to being intrigued by the nature of the investigation to warrant the construction of such a machine. What kind of situation have you encountered that needs a device to scan for all possible and even theoretical psychic energies? Or have you simply become bored idling your days in the sunshine and invented the device for fun?
Either way, I shall not bore you too much with some of the construction details. Suffice to say that mounting the ecto-plasmatic converter on the metallic crypto-zoetrope was quite fiddly and moderately explosive. Luckily for me, I keep a bucket of sand handy for such eventualities.
So as you requested, the device has a moveable sprocket connection to the main psychic flange which allows for adjustment of the measurement range. In short, you should be able to point the device at any object that you suspect may be infused by some magical force and adjust the range of energies measured even beyond that known to us paranormal investigators. The range is quite extensive; you should be able to detect energies both from strange eldritch creatures that live deep in the oceans in sunken cities or even beings from deep outer space, if such things existed! Excuse my fanciful nature, I have been reading some rather strange literature recently.
I hope this finds you otherwise well, and please let me know how your investigation into whatever it is and wherever it is proceeds.
PS – Don’t turn the sprocket all the way to the left, the device is liable to explode
PPS – Or the right
