I thanked him for his thoughtfulness and presence of mind, which seemed to please him.

I have described this, my first meeting with old Frick, so fully, not because it is of any great importance to my story, but because it will, perhaps, give you some idea of the man and his characteristics.

Next I proceeded to examine the scene of the burglary. It was just as Frick had said, nothing had been touched or moved. Even the sack which the thieves had used to stow away their spoil in, lay there on the floor, just as they had flung it from them when they took to flight.

Several of the cupboards in the room had been filled with gold and silver articles, and precious stones. It was a complete museum; and the thieves had, so far, carried out a sensible plan in having broken open all the cupboards and drawers, but only putting into the bag the articles which were of the most value and the easiest of transport. Otherwise, there was little else to discover. We could follow the tracks of the thieves through the garden, over the palings, and out into Drammen Road; but they had left nothing behind them except old Frick's trophy, the heel with the bit of sole adhering, and the sack.

This was emptied, and the contents set in their places in the cupboards. Nothing seemed to be missing; and as each article was numbered, and the place in which it was to stand, it was an easy matter to control them.

Suddenly Miss Frick clasped her hands together, and exclaimed:—

"But the tortoise, uncle! the tortoise is gone!

"It is a precious gem we have given that name—a large diamond set in gold, and in the shape of a tortoise," she added, when she saw my puzzled expression.

"That is the most valuable of all my collection," continued Frick. "I don't know what the diamond can be worth when it is polished, but all I know is that I have been offered £2000 for it as it is now. It is black."

He raked about with his large fingers at the bottom of the sack, and finally turned it inside out, but there was no diamond tortoise. Then the room, and at last the garden, and the nearest part of Drammen Road were searched most carefully by aid of the lantern, but without result.
