CHAPTER VII. THE NUPTIALS OF RUTH WESTMACOTT 

Here was Sir Rowland Blake in high fettle at knowing himself armed with a portentous weapon for the destruction of Anthony Wilding. Upon closer inspection of it, however, he came to realize--as Richard had realized earlier--that it was double-edged, and that the wielding of it must be fraught with as much danger for Richard as for their common enemy. For to betray Mr. Wilding and the plot would scarce be possible without betraying young Westmacott, and that was unthinkable, since to ruin Richard--a thing he would have done with a light heart so far as Richard was himself concerned--would be to ruin his own hopes of winning Ruth. 

Therefore, during the days that followed, Sir Rowland was forced to fret in idleness what time his wound was healing; but if his arm was invalided, his eyes and ears were sound, and he remained watchful for an opportunity to apply the knowledge he had gained. Richard mentioned the subject no more, so that Blake almost came to wonder whether the boy remembered what in his cups he had betrayed. 

Meanwhile Mr. Wilding moved serene and smiling on his way. Daily there were great armfuls of flowers deposited at Lupton House--his lover's offering to his mistress--and no day went by but that some richer gift accompanied them. Now it was a collar of brilliants, anon a rope of pearls, again a priceless ring that had been Mr. Wilding's mother's. Ruth received with reluctance these pledges of his undesired affection. It were idle to reject them, considering that she was to marry him; yet it hurt her sorely to retain them. On her side she made no dispositions for the marriage, but went about her daily tasks as though she were to remain a maid at Lupton House for a time as yet indefinite. 
Does he have any injuries?
