subs. phr. (thieves).Picking pockets under cover of a sham hand or DADDLE (q.v.).
1883. GREENWOOD, in Daily Telegraph. Asked by the friendly warder what he thought of the DUMMY-DADDLE DODGE, Mr. Mobbs said he rather thought that game was played out. A woman, he proceeded to explain, can work with a DUMMY-DADDLE in an omnibus or a railway carriage much better than a man, because, without appearing conspicuous, she can wear any kind of loose shawl or cloak as concealment for her real hand.
