During the process of breaking in, they had reached the top and had made their way in from the inside, moving the marble out of the way. Now, as they were trying to break in from the outside, the marble wasn't as easy to lift as they had imagined, causing Fitzroy Sullivan to exert a lot of effort.
Lola Hussey had calculated the approximate measurements and felt more confident. When she snapped back to reality, she noticed a lot of dirt near her feet – it was all pushed up by Fitzroy Sullivan as he dug the hole.
He had dug quite far, but not too deep, as it would help save time.
Lola Hussey asked him, "Fitzroy Sullivan, is the shovel you're using expensive or not?"
Fitzroy Sullivan managed to squeeze out an answer amidst his busyness, "Not expensive, just five zeros."
"Can I buy one from you after we escape?"
"Of course, we're old acquaintances after all. I'll give you a discount, 100000!"
"..."
He wasn't deceiving her; it was indeed just five zeros!
