“Maybe,” was his reply. “It certainly looks just the sort of outlandish place to hold a mystery. But we must say nothing to anyone. Let’s take our observation in silence. They’ll enjoy their picnic while we will refer to that memorandum you made of the parchment record.”

At that moment Sammy Waldron, ruddy and sun-tanned, in a rough cycling suit, came up and began to chaff Walter regarding the soda—he himself being the bearer of a quantity of that spirit very precious with men on such occasions, being assisted in its transport by the ever humorous Mrs Payling, well turned-out as usual, and brimming over with good humour. Being a widow, with a son in the Indian service, she was essentially a man’s companion as well as being a chic woman. She was chatting with Mr Batten, while Fred Fenwicke was walking with Connie and two ladies of the party a little in advance.

At last we all gained the water’s edge, and, depositing our loads, proceeded to examine the laird’s boat, a key of which Mr Batten had obtained. It was half-full of water, and there were no oars.

After some search a labourer was discovered who knew the spot where the oars were concealed, and he having pointed them out under a hedge, we discovered that they were so badly rotted by the weather that there was scarcely any blade left, and, further, that there were no rowlocks.

Sammy, Godfrey Handsworth, and the two Sales commenced to bale out the water with drinking-glasses, while the rest of the party, now being very hungry and thirsty, sat impatiently on the bank watching, and passing sarcastic remarks upon the slow progress of the work.

At length, however, it was concluded, and some of the provisions were taken aboard: Sammy being elected coxswain, with the two Sales as rowers. Then they took in a male volunteer on the trial trip.

“The husbands’ boat for Margate!”

“Nice day for a sail!” and “Man the lifeboat!” were among the derisive shouts and jeers amid which the venturous party put off into the stormy and rather dangerous waters of the Dee. The course of the boat with such oars and without rowlocks was necessarily erratic, and the absurd antics of the rowers and of Sammy as coxswain convulsed us on shore. Amid-stream the rowers, affecting fatigue, commenced to refresh themselves upon the provisions which we had sent across, and calmly lunched, leaving us hungry and empty.

After a long and tempestuous voyage they landed their first freight; then returned and took a second and a third. In the fourth Wyman and myself were included, and after running on a mud bank and having a very exciting and ludicrous time of it, we at last, laughing merrily, sprang ashore on that wild, unvisited island, where, according to The Closed Book, the wonderful emeralds of Lucrezia Borgia had, through centuries, lain hidden.

Mr Batten assured us that no one had landed there for at least a year or more; but the instant we gained the shore we turned our first attention to discovering any traces of those whom we knew were aware of the old monk’s secret in common with ourselves.
