“I should perhaps report this discovery to the authorities, but I have thought it best to consult you upon the matter before doing so. This letter should reach you by the first post tomorrow (Saturday) morning. I should be glad if you could make it convenient to meet me on the premises at 2 p.m. that day, when the workmen who are at present employed there will have gone. I can then show you my discovery, and we can consult upon the most suitable steps to be taken in the matter. Should you not find this convenient, I shall assume that the subject does not interest you, and shall report the matter forthwith to the police. Yours faithfully, John Lacey.”
