You have lost an item of value on a train. Write a letter to the railway company. In your letter

Dear Sir or Madam, I lost my laptop on a train. It was a grey MacBook Pro color. Top-secret documents from the UK Military agency were saved on HDD

this

computer because you can recognize it by a large label with the text "TOP SECRET".

This

item is very important to me, my mother presented it on my birthday. I went from London to Bristol on the morning train and was sitting

next

to the window at place 10, carriage 5. I think I left the laptop when my station was announced and I was hurrying to the city. Would you be kind enough to look for my notebook computer? I can assume that the train conductor could see my computer. I strongly advise you to ask him. If he doesn't know you can ask the employee at the Bristol railway station. If you find my laptop, please call or text me. Best regards, Vladimir Chilikov
