                                                                                                            of Andrew Mill, Greenfield, Local

The inscription reads:  "Dear John, I know this is just in your line, Florrie"

1904 can be so mysterious sometimes.  What can it mean, "just in your line"?  Do you suppose Florrie was referring to "Line of work"?  Was J Butterworth an aspiring architect or a sculptor or some other variety of artisan with plans to devote his life to decorating memorials to the beloved dead?  Or could she possibly have meant "Line of sight"?  Could John see the Albert Memorial from where he lived or worked?  Or was it a place he enjoyed visiting, a favorite destination perhaps, a rendezvous spot for assignations with Florrie -- or someone else?  Or is "in your line" some kind of slang for "the sort of thing you fancy" or "a matter of taste" or "up your alley"?  And what does that say about Master Butterworth, that the Albert Memorial was the sort of place he preferred to loiter?  For what purpose?  What was he looking for?  Had Florrie discovered young Master Butterworth's real line of work?   

Did Florrie intend her message as a veiled threat perhaps, to expose the young Butterworth?  Or was it even more than that, political in nature, an anarchist's obscure and now long forgotten message in code?

So far I've been able to discover that Andrew Mill was a textile mill, or had been at one time.  And there were Suffragettes in Oldham around 1904.  Thank you, world wide web. 

Any additional information or light you may be able to shed on this mystery, however, would be deeply appreciated.  After all, it surely means something.  Don't you think?
