Something I noticed, I wonder if anyone else did: there seem to be glaring errors that are just too obvious to be down to accidents or ignorance. A really big one is that Patience has been left a puzzle box by her mother. A yellow Post-It note bears a 5 digit number - a clue. In one episide of series 2, Patience excitedly reveals she recognises the number as a mathematical curiosity: a "vampire number", which is the product of two numbers that have the same digits as the resultant product. There's a Wikipedia page on them. Trouble is, vampire numbers must always have an even number of digits.
I managed to watch Patience again on those bootleg Youtubes, which means unlike when I had to watch it live with no chance to pause and rewind, I can play it over and over again until I get the full dialogue and details.
It turns out that the number was not the vampire number itself, but - as Patience utters - one of the fang numbers, so it can have an odd number of figures. No goof after all. Huzzah! All is well!
Or is it ... Now, the five digit number Patience found was 90831, and then she works out the vampire number, which must have 10 digits. (It turns out to be an old case number.) However, I just checked Al Sweigert's blog on
Vampire Numbers Visualized (
https://coffeeghost.net/2011/07/19/vampire-numbers-visualized/), in which he kindly offers a zip file of all vampire numbers up to 10 digits long, and there are 15 matches:
Code:
Fang 1 Fang 2 Vampire No.
90831 11022 1001139282
90831 11220 1019123820
90831 12201 1108229031
90831 15477 1405791387
90831 22659 2058139629
90831 25971 2358971901
90831 34035 3091433085
90831 39651 3601539981
90831 42000 3814902000
90831 54627 4961825037
90831 55437 5035398147
90831 56544 5135948064
90831 65022 5906013282
90831 69243 6289410933
90831 77451 7034951781
So, the actual goof seems to be that Patience only finds one case number, not 15 of them (which the
real Patience would have done!) Ah well. Love that series anyway!
