When Zach had accepted the undertaking that was the bookshop, he had promised himself to continue Horton's tradition of treating his staff like family. This came with certain pros and cons. In the case of Jo's letter, it had meant his manager had found a discrete way to present it to him. However, it had also invited a barrage of queries that he had not been equipped to answer. Who was Jo? Why did they have access to his private floo? What was so urgent that an owl wouldn't suffice?

In true Zach fashion, when faced with discomfort, he simply apologized profusely, blushed, and disappeared with the promise of an explanation forthwith. Although, how detailed or expedient that account would end up being was anyone's guess.

Instead of simply stowing away in the back room like a normal person would, he turned on his heel, quickly crossed the shop, stepped into the public floo, and disappeared.

It would be several hours and an incendio later that he owled his rather short reply.

Dear Jo,

It is wonderful to hear from you. I had grown worried that something grave had occurred.

I sincerely apologize for any undue stress visiting my old flat might have caused. I longed for a change of scenery and have recently moved house. I meant to inform you; I wasn't sure you wanted to hear from me neglected to send the letter.

I have enclosed said letter and my new address. You are welcome to call here, or I would be happy to meet you at any location you prefer.

I do hope you are well.

Zach
