With a satisfied nod Robert relieved me of my burden, and having paid the cabman, we started off together up the jetty.
"There's no reason why you shouldn't shove off at once," I added, "not if you're in a hurry. We can't do anything here till Campbell arrives."
"I suppose I ought to," said Bobby rather doubtfully. "All the same, I'm not over keen on leaving you alone."
He stepped down with the hamper into the dinghy, and I took my place at the tiller.
"I shan't get into any mischief," I assured him. "I shall take Campbell's tip and lock myself up in the house with a loaded revolver. He's heard the whole yarn and he quite approves of our present arrangements."
As briefly as possible I went on to describe my interview in Angel Court and the dramatic news which the Inspector had given me with regard to Manning's real identity.
"I always knew he was a bad egg," grunted Bobby, tugging away grimly at his oars. "It's uncommon lucky for you that you happened to make a hit with that girl of yours. If it hadn't been for her——"
He left the sentence unfinished, and with a few vicious strokes ran up alongside the motor-boat, where Jenkins was awaiting our arrival.
"Well, you pop off," I said, preparing to take his seat. "I've told Campbell to look out for you on the platform, so you can't very well miss each other. I'll expect you back here about eight-thirty."
Bobby clambered on board, and, waving him farewell, I rowed on to the landing-stage, where I proceeded to disembark. I stood there until they had cast off their moorings and were heading out into the estuary; then with the hamper on my shoulder I trudged off towards the house.
