The other day I was sitting in my local tavern, The Spyglass, which overlooks the sea, when in sailed my old friend the pirate Captain Conan Drum. "Well, shiver me barnacles!" he roared on seeing me. He too is a bit of a puzzle addict and so, after joining me for a glass of milk and telling me about his latest exploits on the high seas, he couldn't resist showing me his latest conundrum.

He reached into one of his jacket pockets and produced seven gleaming £5 coins, which he then proceeded to arrange on the table in front of me exactly as shown below. "Now, me lad." he said, with a mischievous look in his eyes. "I'll wager you'll not be able to solve this one. Take away two coins from this here arrangement to leave five coins across and three coins going down."

It was clear the wily old sea dog still had one or two tricks up his sleeve, as I couldn't for the life of me see how it could be done. Can you see through his skulduggery and solve it?

Below are four proverbs, however, each letter has been replaced by its position in the alphabet, but the spaces between the resulting numbers have been removed and new spaces added.

For example, DOG becomes 4 1 5 7.

What are the proverbs?

1 2 9 1 1 5 6 1 2 0 8 5 1 8 1 2 9 1 1 5 1 9 1 5 1 4

1 2 9 1 1 5 1 3 1 5 2 0 8 5 1 8 1 2 9 1 1 5 4 1 2 1 7 8 2 0 5 1 8

1 2 1 4 1 6 5 1 4 1 4 2 5 1 1 2 2 3 1 2 5 1 9 2 0 2 1 1 8 1 4 1 9 2 1 1 6

1 0 2 1 4 7 5 1 4 1 5 2 0 2 0 8 1 2 0 2 5 5 2 5 1 4 1 5 2 0 1 0 2 1 4 7 5 4

Your objective is to place some diagonal mirrors into the grid.

If a ray of light is shone in to the grid from each of the letters, and allowed to bounce off the internal diagonal mirrors, each will exit the grid at the twin of the letter that it entered the grid. For example, a ray entering at either letter D will bounce off some mirrors and exit the grid at the other letter D.

Each row and each column will contain exactly two of the diagonal mirrors.
